Hint: To answer this question we have to know about the preparation of chlorine dioxide. Chlorine dioxide is highly oxidant and it can be prepared by passing dry chlorine over silver chlorate.
Complete Step by Step Answer:
Chlorine is a halogen element. Chlorine dioxide is the oxide of chlorine.
On passing dry chlorine over silver chlorate chlorine dioxide is prepared along with silver chloride and oxygen gas.
The reaction can be given as follows:
$2AgCl{{O}_{3}}+C{{l}_{2}}\to 2AgCl+{{O}_{2}}+2Cl{{O}_{2}}$
Thus in this reaction two moles of silver chlorate react with one mole of dry chlorine to produce two moles of chlorine dioxide along with two moles of silver chloride and one mole of oxygen gas.
Thus the correct option is D.
Additional information: Chlorine dioxide is highly oxidant. It can be used to kill bacteria, viruses etc present in laboratory, clinic, home etc. That’s why chlorine is widely and highly used in sterilisation of medical clinics, medical laboratories, rooms etc.
Note: Chlorine is a group $17$ element. It is also known as halogen element. It generally exists as a gas at room temperature. It is a greenish-yellow colored gas and has the atomic number of $17$.
