Max moment occurs at center. So. Take the sum of the moment.
At A is zero, By * L = M,
So the sum of vertical force = 0, By + Ay = 0.
We got Ay = -M/L. So, M/2 is the correct answer.
At A is zero, By * L = M,
So the sum of vertical force = 0, By + Ay = 0.
We got Ay = -M/L. So, M/2 is the correct answer.

I too agree with the answer a) M.

The answer is M because pinned support don't carry any moment i.e. zero moments (Decreasing moment towards the either support in this case) and here is clear that couple M is applied at midspan so center carries maximum bending moment.

It is m. Because at centre, the moment will be m/2 that means its half of moment. Max is m. So the answer is m.

I think the correct answer is M/2.

The answer should be M.

I also think the correct answer is M/2.

M/2 is the correct answer.

Maximum moment in this case will be M but maximum bending moment will be M/2.
As bending moment at a section is sum of the moments either to the left or right of the section.

According to me, the answer is M/2.
