If the question had stated linear strain, then then the answer is true. If there is a compressive stress, then there will be a Linear compressive strain and Lateral tensile strain.
So, the answer is false.
So, the answer is false.

He saying that length is reduced means due to the compressive force only.

Stress is the internal force applied by the body to oppose the applied force. So if force is compressive stress should be tensile.
And strain of course will be compressive.
So correct answer is false.
And strain of course will be compressive.
So correct answer is false.

Generally stress is ratio of load to area. If the load is compressive then the stress is called compressive stress.

When bar is stretched stresses are tensile. If forces are reversed compressive stresses will be there.

Inwards pushes is called compressive stress.

The answer should be option B, because as a result of pushes the body tends to reduce its length which means the applied forces are compressive in nature, now we know the stress is internal resisting force, therefore the resisting force will be tensile in nature i.e., stress and strain induced are tensile.

When the body is subjected pushing forces on both side having equal and opposite direction, so the stress produces in the body will be Tensile stress.

We push that body. The length of the body is deceased. So that body try to become its original length. So creating stress is oppose that push. It is called tensile stress.
