Explanation:

To segment business school alumni by Household who work for Fortune 500 companies, the consultant should use the Contact and Account report type. This report type allows you to:

Start with Contacts (alumni)
Include related Account data (such as employer organizations)
Apply Cross Filters to narrow results to Contacts with specific Affiliations (e.g., business school)
Group or filter by Household Account and employer Account attributes (e.g., Fortune 500 status)

This setup supports complex segmentation by leveraging both Contact-level data and Account-level relationships, which is ideal for advancement targeting and campaign planning.

❌ Why the other options don’t fit:
B. Contact and Affiliations report: Useful for viewing affiliations, but lacks direct access to Account-level fields like employer industry or Fortune 500 status
C. Contact and Relationships report: Focuses on person-to-person connections (e.g., mentor/mentee), not organizational affiliations or employment
