Displacement-time curve of a particle moving along a straight

Question

Displacement-time curve of a particle moving along a straight line is shown. Tangents at $A$ and $B$ makes angle $45^{\circ}$ and $135^{\circ}$ with positive $x - a x i s$ respectively. The average acceleration of the particle during $t = 1, t = 2$ seconds is

- 2 m / s^{2}

1 m / s^{2}

- 1 m / s^{2}
