B is the right answer. Draw separate stress diagrams. For self-weight, we will get a triangle (tensile) with zero at top and max at the bottom. Due to load, we will get rectangle (p/a compressive). So the max value of stress will be at the top (compressive)

Option B is correct.
For Eg;
When one boy (no 1) is hanging from the roof and his leg was holded by another boy (no2) hanging and the second boy's leg hold by another boy (no3) hanging.
So which boy will experience more stress.? Exactly the boy no1.

Due to external load stress distribution is uniform and due to the self weight stress distribution changes linearly from zero at top to maximum at its bottom. So option A is correct.

At every point of the bar due to stress is force/area resisting force per unit area d is correct.

Think of a column which is loaded from top side but it often crushes at its lower portion.

Because its weight is maximum at the top.
