$A$ particle of mass $m$ is released from $a$ height $H$ on $a$ smooth curved surface which ends into a vertical loop of radius $R$, as shown If $\theta$ is instantaneous angle which the line joining the particle and the centre of the loop makes with the vertical, then identify the correct statement $(s)$ related to the normal reaction $N$ between the block and the surface

A

The maximum value $N$ occurs at $\theta = 0$

B

The minimum value of $N$ occurs at $N = \pi$ for $H > 5R/2$

C

The value of $N$ becomes zero only when $\theta \geq \pi /2$

D

All of the above
