Explanation

Here is the step by step breakdown to find what C wore.

First, determine the pant colours. We know B wore orange pants. A did not wear green pants, so A must have worn yellow pants. This leaves green pants for C.

Second, determine the shirt colours. We know no person wore the same colour shirt and pants. Since B wore orange pants, B could not wear an orange shirt. Since the problem also states B did not wear a blue shirt, B must have worn the black shirt.

Now consider A. A wore yellow pants. We know A did not wear a black shirt. Since B already took the black shirt, A must have worn either blue or orange.

Now consider C. C wore green pants. We know C did not wear an orange shirt. If C did not wear orange, and B is already wearing black, C must have worn the blue shirt.

Therefore, C wore green pants and a blue shirt. The correct option is B.

Logical Reasoning: Three people A, B and C wore shirts of black, blue and orange colours (not necessarily in that order) and pants of green
