Correct Answer is D

Explanation

A. It is easiest for the client to learn: While the ease of learning is important, the primary goal is effective detection of masses.

B. It takes the least amount of time: The time taken is less critical than the effectiveness of the technique in detecting abnormalities.

C. It causes the least amount of pain: Minimizing pain is not the main reason for choosing a particular technique; effectiveness in detecting masses is more critical.
