To answer the question, we need to understand the different conformations of a molecule. In this case, we are rotating the conformation of a molecule about the C2-C3 bond anticlockwise by an angle of 120°.

Let's analyze the options:

A) Fully eclipsed conformation: In a fully eclipsed conformation, the substituents on adjacent carbons are directly aligned with each other, causing maximum steric hindrance. This is not the conformation obtained by rotating C2 anticlockwise by 120°.

B) Partially eclipsed conformation: In a partially eclipsed conformation, the substituents on adjacent carbons are partially aligned with each other, resulting in some steric hindrance. This is also not the conformation obtained by rotating C2 anticlockwise by 120°.

C) Gauche conformation: In a gauche conformation, the substituents on adjacent carbons are staggered, but not fully aligned. This conformation can be obtained by rotating C2 anticlockwise by 120°.

D) Staggered conformation: In a staggered conformation, the substituents on adjacent carbons are fully aligned, resulting in minimum steric hindrance. This is not the conformation obtained by rotating C2 anticlockwise by 120°.

Based on the analysis, the conformation obtained by rotating C2 anticlockwise by 120° is C) Gauche conformation.
