Thyristor $T$ in the figure below is initially off and is triggered with a single pulse of width $10$ $μs$. It is given that $L=\bigg(\dfrac{100}{\pi }\bigg)\mu H$   and $C=\bigg(\dfrac{100}{\pi }\bigg)\mu F$.  Assuming latching and holding currents of the thyristor are both zero and the initial charge on $C$ is zero, $T$ conducts of

1. $10\mu s$
2. $50\mu s$
3. $100\mu s$
4. $200\mu s$
