Answer:

C. 1

Explanation:

Group 1 metals are highly reactive (such as Sodium) and form 1 to 1 ratio of ions with halogens (such as chlorine, bromine etc).

This happens because group 1 element can donate 1 valence electron to fulfill their octet rule and halogens can receive 1 valence electron to fulfill their octet.
