Same is the right answer.

I think it will be same. Agree @Apcivilian.

The right answer is A because elastic strength Z. Doesn't depend on Length.
z = bd2/6.
Same is answer.
z = bd2/6.
Same is answer.

4 times as section modulus --> bd^2/6.

If length, width are remains same and depth is double that of A then what's the elastic strength of B?

Strength of beam can be calculated by formula R = 1.5PL/bh^2.
Hence right answer.
Hence right answer.
