What if the washer Removed and tightened with a nut only? Please explain.

The bolt is under tension. And washer is under compression.

While tightening against washer bolt is pulled axially that's why tensile stress is induced.

Actually, Washer experience compressive stress. Whereas Bolt during advancement experience tensile and torsion, irrespective whether it has washer or not.

Shouldn't the answer be compressive stress?

The bolts start to stretch elastically, proportional to the amount of nut advancement. As the nut is further turned the threads of the bolt and nut are forced together under enormous pressure generating friction between the mating threads and also causing tensional twisting to the body of the bolt between the clamped surfaces. The bolt is experiencing two forces simultaneously, tension and torsion.
