First of all, where is A and where is B we can't assume on our own.

In simply support the end moments are zero.

Reaction.
Ra + Rb = 1 * 10 = 10..........(1).
Rb * 10 = 10.
Rb = 1.
Put, Rb in above equation then,
Ra = 9.
The moment at A point.
M = 1 * 10 - 1 * 10 = 0.
The moment at A is zero this is answer.
Ra + Rb = 1 * 10 = 10..........(1).
Rb * 10 = 10.
Rb = 1.

The moment at A point.
M = 1 * 10 - 1 * 10 = 0.
The moment at A is zero this is answer.

This problem can be solved by using propped methods.
First find middle support reaction using super imposition principle (compatability eqn) at deflection where the middle support =0.

No need to calculate simple assumption at any support, the reaction will always be zero.

It's 1.875 by three moment theorem.

Ra + Rb = 10t
Ra = 10t - Rb,
Therefore to find Ra take moments about A.
Rb = 10t-10t = 0.
Therefore, option A is correct.
Ra = 10t - Rb,
Therefore to find Ra take moments about A.
Rb = 10t-10t = 0.
Therefore, option A is correct.
