Theory of Structures
Pick up the correct statement from the following:

In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area
All of these
In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment
In a loaded beam, the moment at which the first yield occurs is called yield moment
