I have been asked this question in semester exam.

My query is from Internal Forces Developed in Structural Members topic in section Internal Forces of Engineering Mechanics

Correct choice is A. 55N

To explain: First represent the forces in their vector form. Then equate the net sum of the forces in the x, y and z directions to be zero. You will get FB = FC and 2(.848) = 40N. This gives the answer as 23.6N.
