Solution

The correct option is B $1 m / s$
Given,
Mass of the gun, $m_{g} = 10 k g$
Mass of the bullet, $m_{b} = 30 g = 0.03 k g$
Velocity of the bullet, $v_{b} = 330 m / s$
Velocity of the gun, $v_{g}$
By applying the conservation of linear momentum,
$m_{g} v_{g} = m_{b} v_{b}$
$10 \times v_{g} = 0.03 \times 330$
$v_{g} = 1 m / s$
