It is decreased because for mass m1 it has more friction than m2 so, when angle increased due to friction acceralation is decreased.

Here, a = (m2-m1sinθ)g/m2.

T-mgsin(θ)= m1a.
So, if θ increase acceleration decreases.
So, if θ increase acceleration decreases.

They have not mentioned neither smooth surface nor rough one, so answer will be unpredictable.

Whatever may be the values of mass, as angle increases component of acceleration of body B will become more close to body A as difference decreases so net acceleration will decrease.

It depends upon masses of two bodies. We have to know which side mass is heavier. Then only we can get acceleration direction and further can be solved.

Acceleration = dv/dt.

If M1 is sliding down then the acceleration of the system will decrease and if M1 is sliding up then the acceleration of the system will increase.

The answer of this question as mentioned is valid only when m2>m1.

Whatever the case is m2>m1 or m1>m2 the answer is B acceleration decreases.
Because in whatever direction the system travels the component of gravity along the plane is mgsinA ndn it will increase as A (Angle of inclination increase).
