If bending moment not the same throughout the section the meaning is bending stress is also not the same throughout the section this is the logic so in my consideration option E is correct.

As per my knowledge, the right answer and the Necessary condition is Z is directly proportional to M at every section.
Z= Section modulus.
M= Moment.
Z= Section modulus.
M= Moment.

In a beam of uniform strength, either the cross-section is varied (tapered) or material properties are adjusted.
So that: σ =M/Z =constant.
So that: σ =M/Z =constant.

Beam is said to be uniform strength if at every section along its longitudinal axis, the bending stress is same.

A is correct because z constant but bm and stress variable and if moment constant then stress also constant.

The strength of any beam depends upon its material and its cross-section. So, E is correct.

But M is directly proportional to Z so bending stress is the correct answer.

I think the bending stress is the same throughout is the correct one.

I think A is the perfect answer.
