l/2 √3 = 0.288 l (distance from crown).
So, distance from side = l/2 - 0.288 = 0.211.

Agree, Option C is correct.

I think A is the correct option.

a) When a concentrated load acts maximum positive moment occurs at distance 0.2113L from either end. And maximum negative moment occurs at 0.25L from either end.

b) When UDL acts maximum positive or negative moment acts at a distance 0.234L
So the suitable option will be L / 2√3.

I think Question is asking for a distance of maximum positive B.M which has a value (0.2113) L from either side and distance of maximum negative B.M is L/4.
