In SHM,

\begin{aligned} & \mathrm{F} \propto-\mathrm{x} \rightarrow \mathrm{A} \\ & \mathrm{a} \propto-\mathrm{x} \rightarrow \mathrm{B} \\ & \mathrm{V}_{\text {mean }} \rightarrow \max \text { imum } \rightarrow \mathrm{c} \\ & \mathrm{a}_{\text {extreme }} \rightarrow \text { maximum } \end{aligned}

Hence, (A), (B) and (C) are true.
