Step 1: Understand motivation in selling:
Motivation has three parts: direction, intensity and persistence. Intensity of desire shows how strongly a person wants to reach the goal.

Step 3: Check the options:
Option (A) talks about time and effort spent to convince the customer. It is about the selling act, not the desire.
Option (B) lists knowledge and skill, which are abilities.
Option (C) talks about commitment, which is closer to persistence.
Option (D) gives the amount of physical and mental effort the salesman is ready to put forth. It fits.
