This question was addressed to me during an internship interview.

Question is taken from Conditions for a Rigid-Body Equilibrium topic in section Equilibrium of a Rigid Body of Engineering Mechanics

Answer 1

Correct option is (d) There are various types of support for the beams and they are countless

Easy explanation: The support is the thing which a human decides. That can be anything. That is the support can be given in any way. The type of support also is important as different types of supports have different conditions for the equilibrium.
