Answer is Wrong!
The correct answer is C. Betterment.

B. Advancement is progress or improvement.
C. Betterment is the act of making something better or the state of being better.
D. Preference is the act of choosing one thing over another.
Betterment is the most appropriate synonym for improvement because it refers to the act of making something better or the state of being better. Promotion and advancement can also refer to improvement, but they are more specific in that they refer to an increase in rank or position. Preference is not a synonym for improvement because it refers to the act of choosing one thing over another.
