The answer C is correct. Regarding B, you will not get zero or equilibrium if you sum just the forces. By this I mean, not resolving inclined forces into their components will make a wrong result. You can't add the inclined forces at an angle directly with forces that are non-inclined (angle=0). Thus first resolve all of the forces into horizontal and vertical components, sum them and see the value. I hope you understood it.

I am unable to get an answer from anywhere. Where I had checked there is a different answer so please explain the correct answer.

The answer should be 'B.
To be in equilibrium sum of resolved part in both vertical and horizontal direction should be zero.
To be in equilibrium sum of resolved part in both vertical and horizontal direction should be zero.

Equilibrium means the sum of all forces or the sum of resolve part, where both the horizontal and vertical direction is zero.

The sum of the resolved parts in any two perpendicular directions are both zero.

Answer - sum of resolved part in vertical and horizontal direction is zero.

Actually, the VECTOR sum of forces must be zero, not the sum of forces.

This should also include the verticle components of the forces.

Yes, Even I think the answer should be B.
