I guess is B because if all sides of the cube are 1 then the sides that forms the triangle BEG will be all root of 2, hence will have equal sides... 60 degrees.

Explanation:
Join BE, EG and GB which are the diagonals of the faces of cube
Let edge length of the given cube be \(a\), then BE = EG = GB = \(\sqrt{2}a\)
Thus, BEG is an equilateral triangle with each angle 60°
Col. A: 60°
Col. B: 90°
Hence, option B
