a.

The acceleration at A is positive and less than the acceleration at B.

b.

The acceleration at B is positive and less than the acceleration at A.

c.

The accelerations at A and B are each zero.

d.

The accelerations at A and B cannot be determined.

This is a speed/time graph.
The slope of the graph at each point is the time rate of change of speed
at that point, and THAT's the definition of the magnitude of acceleration.

The slope of the curve is zero at both ' A ' and ' B ', so acceleration is
zero at both of those points.

That seems to be exactly what choice-c says.

When you take the derivative of a straight line, it is zero.
