Solution

The correct option is A True
$n_{a i r}$ $s i n θ_{a i r}$ = $n_{w a t e r} s i n θ_{w a t e r}$

$\Rightarrow \frac{n_{a i r}}{n_{w a t e r}} = \frac{S i n θ_{w a t e r}}{S i n θ_{a i r}}$ , which is Snell's law.

$n_{a i r}$ $s i n θ_{a i r}$ = $n_{w a t e r} s i n θ_{w a t e r}$

The correct option is A True
$n_{a i r}$ $s i n θ_{a i r}$ = $n_{w a t e r} s i n θ_{w a t e r}$

$\Rightarrow \frac{n_{a i r}}{n_{w a t e r}} = \frac{S i n θ_{w a t e r}}{S i n θ_{a i r}}$ , which is Snell's law.
