A
Acetic acid + Ammonia
B
Carbon dioxide + Ammonia
C
Methane + Carbon Monoxide
D
Ammonium Chloride + Calcium sulphae
Explanation: 

Detailed explanation-1: -Ammonia is combined with carbon dioxide to form urea in kidney.

Detailed explanation-2: -Urea (CH4N2O) is a common fertilizer that is synthesized by the reaction of ammonia (NH3) with carbon dioxide: 2 NH3(aq) + CO2(aq)¡CH4N2O(aq) + H2O(l ) In an industrial synthesis of urea, a chemist combines 136.4 kg of ammonia with 211.4 kg of carbon dioxide and obtains 168.4 kg of urea.

Detailed explanation-3: -Urea (NH2)2CO ( N H 2 ) 2 C O is prepared by reacting ammonia with carbon dioxide. The byproduct is water. 637.2 g of ammonia are reacted with 787.3 g of carbon dioxide.
