Comprehensive and Detailed Explanation (150–250 words):

A residential property manager typically handles marketing, tenant screening (within fair-housing compliance), lease negotiation and execution, rent collection, coordination of maintenance, and reporting to the owner. Of the choices, negotiating leases between the owner and prospective tenants (D) squarely fits the manager’s role. Option A (wage garnishment) is a legal remedy available only through court order—not something a manager can unilaterally request from an employer. Option B (deciding structural changes) exceeds a manager’s authority; capital improvements require owner approval. Option C is problematic: attempting to “select tenants to provide a diverse environment” risks steering or discriminatory practices in violation of fair housing laws; tenant selection must be based on neutral, consistent criteria (income, credit, rental history) applied uniformly. Massachusetts exam content highlights the manager’s duty to act within the management agreement, comply with fair housing, and conduct lease negotiations consistent with owner directives. Therefore, D is the correct answer.
