Solution

The correct option is D $H_{2} S$
$R - X + M g E t_{2} O - -- \to R M g X (Grignard reagent)$
Amine, alcohol, $H_{2} S$ and carboxylic acid all contains acidic hydrogen and grignard reagent acting as strong base take up proton to form alkane.

$A . R M g X + R^{'} N H_{2} Dry Ether - ----- \to R H + M g X (N H R^{'})$
Mechanism:

$B . R^{'} - O H R M g X - ---- \to Dry ether R H$

$C . R^{'} - C O O - H R M g X - ---- \to Dry ether R H$

$D . H_{2} S R M g X - ---- \to Dry ether R H$
