m1a-T = T-m2a.

Therefore T = (m1+m2)a/2 = X(say).

Now if masses are halved, then tension = X/2 = T/2.

Since T= (m1*m2/m1+m2) g.

So, tension will be halved (T/2) when both m1 & m2 are halved.

2T= (m'g+m"g).

Now 50% reduced from both:
2T* = .5(m'g+m"g) = .5X2T.
T* = .5T.

Since T= 2(m1*m2/m1+m2) g.
If we put the value of mass half.
So, the answer is [A].
