Answer:

Halogens chemical family has reactive diatomic molecules in gaseous phase. 

Option: C 

Explanation:

Halogens are the materials which produce salt when these are reacted with metals. Diatomic molecules are composed of two atoms with same or different chemical elements. The elements in group 12 of the periodic table are halogens.

Fluorine, Iodine, Astatine, Bromine, Chlorine and Tennessine are halogens. These are situated on left side of noble gases on periodic table. Halogens form octet with one more electron as they have only seven electrons in valence. These qualities make halogens more reactive than any other non-metals in the groups.
