In SHM, acceleration versus displacement (from mean position) graph

The correct option is A none of the above
The graph is passing through origin and graph is not straight line it is curve

if a is the amplitude and x is mean position and $x_0$ is the position after oscillation.

$a={\omega }^2(x-x_o)$

So, graph is having slope at $-{\omega }^2$

So, option A, B and C are wrong.
