in option C in ist compound O show -I effect as due to bulky methyl group it is no more planar. But in 2nd compound O show its usual nature of +M.

im not much convinced with your last explanation.. i think in option C both are equally acidic. but i guess in first option second molecule is more acidic because of less +I effect of methyl group due to distance
