The correct answer is:
$\alpha=\frac{\omega a}{v}$
Centripetal acceleration,
$\because$
$$
\alpha=\frac{\omega}{t}
$$
$\therefore$
$$
\begin{aligned}
\alpha &=\frac{\omega v}{v t} \\
&=\frac{\omega a}{v}
\end{aligned}
$$
$\because$
$$
\alpha=\frac{\omega}{t}
$$
$\therefore$
$$
\begin{aligned}
\alpha &=\frac{\omega v}{v t} \\
&=\frac{\omega a}{v}
\end{aligned}
$$
