Answer: A) Moment
Explanation:
For a pinned joint support, load are acting either in shear, axial and compression load but not moment.
A pinned joint support allow to circulate the structural member but it is not move in any direction. Pinned joint hold two and more elements together efficiently without any friction connection. That is why, it resist moment load.
It basically transfer vertically and horizontally shear load and cannot resist any moment load. A pinned joint connection work efficiently as lapped joint.
