I'm not getting it clearly. Please explain me in detail.

Only said strain theory not strain energy hence given answer is right.

1. Maximum shear strain energy theory = Von Mises Hencky theory.
2. Max. Strain energy theory = Haig's theory.
3. Max shear stress theory = Guest's or Trecas' theory.
4. Max principal strain energy theory = St. Venants theory.
5. Max principal stress theory Rankine's theory.

Answer is D, Saint Venant's theory is for Principal Maximum Strain Thoery.

Maximum principal stress theory by Rankine.

Maximum strain energy theory by Haigh's. Maximum Principal strain theory by St.Venant's.

So answer must be D.
