Here, m1a=T−m1g...(1)
m2a=m2g−T...(2)
(1)+(2),a=m1+m2m2−m1g
Acceleration of m1, a1=−a= m1−m2g/ m1+m2
For this calculation, we assume that the string is massless and rim of the pulley is frictionless otherwise there would have been a frictional force and mass of string included in the acceleration expression. The tension will come due to the inextensible string, otherwise. the elastic effect would have to be included in the tension. The mass of the pulley does not affect the given expression as tension on both the sides remain the same. Thus, option C is correct.

The answer is 'c'Because eventhough we take the pulley as a mass containing body or a massless body it won't effect the final answer BECAUSE THE PULLEY IS FIXED
