Solution

The correct option is D high
$C H_{4} + C l_{2} h v - \to C H_{3} C l + H C l$
To obtain high yields of $C H_{3} C l$ , the ratio of $C H_{4}$ to $C l_{2}$ must be high, otherwise if we take low ratio of $C H_{4}$ to $C l_{2}$ i.e. excess $C l_{2}$ has been used then there will be formation of more than mono substituted products i.e. $C H_{2} C l_{2}, C H C l_{3}, C C l_{4}$
