When we are pushed in opposite direction automatically the body will be reduced.

My answer is B.
When the body is subjected to two equal and opposite pushes (push is generally compressive in nature) then force is compressive which leads to tensile stress at both ends. As force is compressive there is a decrease in cross section of the body which means compressive strain but stress is tensile.

I think, B is right.

Opposite forces are like that compressive forces, so stresses induced to the body the dimensions of body would be change.

If the compressive stress (Pushed equally on both side) applied on the axis of a rectangular bar of length L, there is a reduced deflection in length L. According to the Question "the stress and strain induced is compressive or not". So due to compressive stress the length is reduce so the answer is 'true".

When a body is being pushed then the arrived stresses should be tensile. But the answer is given compressive. HOW IS IT POSSIBLE IF ANS IS TRUE?

The right answer is A. As the body is pushed hence the tendency of body will be to extend its length.

Stress is tensile because force compressive and strain is compressive.

Stress is compressive but strain in axial direction would be compressive whereas in transverse direction it must be tensile.

If we push the body to reduce the length, the reaction would be an equal and opposite tensile force and hence tensile stress.
