Solution

The correct option is B $A s$
Marsh test is used for the detection of arsenic. To the sample, arsenic-free zinc and sulphuric acid are added. If the sample contains arsenic, then arsine gas $(A s H_{3})$ is obtained.
$A s_{2} O_{3} + 6 Z n + 6 H_{2} S O_{4} 2 \to A s H_{3} + 6 Z n S O_{4} + 3 H_{2} O$
