Yes, you are right, thanks @Raj.

@Ram.
The load is not doubled width is being doubled. So the answer will be 1/2.

I don't understand how it is 1/2?
Clearly said in the question that the load is doubled.
So the formula for deflection is Wl^3/48EI. So that W=2W so it is doubled.
@Yuvrahsinh
Here it didn't ask for the ratio of deflection.
I think option A is correct.

It is 8 times only. 1/ 2 for cantilever.

The question is wrong it should be length Instead of width.
Or if the above question is not wrong then answer will be 1/2.

I think Wl^3/48EI / 2Wl^3/48EI = 1/2.
