Solution

The correct option is A 1000 ml
The required equation is:

$C_{2} H_{2} + \frac{5}{2} O_{2} ⟶ 2 C O_{2} + H_{2} O$

$1$ ml of $C_{2} H_{2}$ reacts with $2.5$ ml of $O_{2}$ .

$400$ ml of $C_{2} H_{2}$ will react with $2.5 \times 400$ $= 1000$ ml.

Hence, the correct answer is option $B$ .
