Question stem:- \(\angle{ACY}=?\)
St1:- MN is parallel to AB
We need at least one of the measures of the angles at the intersection of 3 lines.
Insufficient.
St2:- MPY is 108°.
No relationship between line AB and MN is provided.
Insufficient.
Combined, we have MN || AB
Note:- Corresponding angles formed by 2 parallel lines(MN & AB) and its transversal(here XY) are equal.
So, \(\angle{ACY}=\angle{MPY}=108°\).
Sufficient
Ans. (C)
