Explanation:

To invoke the Bioinfo System API using its REST Connector in a Mule project, the developer needs to add a element in the POM file to include the REST Connector as a dependency. Option E shows a tag with the correct structure: , set to mule-plugin-bio-info, set to 1.0.0, and set to mule-plugin. This configuration ensures that the Mule plugin for the Bioinfo System API, published to Anypoint Exchange, is downloaded and integrated into the project during the Maven build process. MuleSoft’s documentation on creating and using custom connectors (Mule 4) specifies that a element is used in the POM to reference a Mule plugin (e.g., a REST Connector) from Anypoint Exchange, making option E the appropriate choice.

Incorrect Answers:

A. Option A
Option A shows a tag with , set to mule-plugin-bio-info, set to 1.0.0, and set to mule-plugin. A element defines a location to resolve artifacts but does not directly include the plugin as a dependency for the project. To use the REST Connector, the plugin must be added as a (not a ), so option A is incorrect. MuleSoft’s Maven guide clarifies that is for artifact resolution, while is for applying the connector.

B. Option B
Option B shows a tag with , set to mule-plugin-bio-info, set to 1.0.0, and set to mule-plugin. The tag is not a valid POM element in Maven or MuleSoft’s configuration. The correct element to include a Mule plugin (like a REST Connector) is , making option B incorrect. MuleSoft’s documentation on REST Connector integration emphasizes using the tag in the POM.

C. Option C
Option C shows a tag with , set to mule-plugin-bio-info, set to 1.0.0, and set to mule-plugin, followed by another and for rest-connect. A element is used for Java libraries, not Mule plugins or connectors, which require a element. Additionally, including rest-connect as a separate artifact is unnecessary and incorrect for invoking the Bioinfo System API’s REST Connector. MuleSoft’s POM configuration guide specifies that Mule plugins use rather than .

D. Option D
Option D shows a tag with , set to mule-plugin-bio-info, set to 1.0.0, and set to mule-plugin. While the artifact details are correct, using instead of is wrong. Mule plugins, including REST Connectors from Anypoint Exchange, must be declared as elements in the POM to be recognized and executed by the Mule runtime. MuleSoft’s documentation on Mule plugin development confirms that is the required tag for integrating custom or exchange-published plugins.

Additional Context:
The Bioinfo System API’s REST Connector, published to Anypoint Exchange, is a Mule plugin that provides pre-built operations to interact with the API. Adding it as a in the POM ensures that Anypoint Studio or Maven downloads the plugin and makes its operations available in the project’s palette or XML configuration. The value mule-plugin indicates the artifact is a Mule-specific plugin, which is standard for connectors.

Summary:
Option E is correct because the element in the POM is the proper way to include the Bioinfo System API’s REST Connector from Anypoint Exchange. Options A (), B (), C ( with extra artifact), and D ( alone) are incorrect because they use inappropriate or incomplete POM elements for integrating a Mule plugin.
