Solution

The correct option is A $B r, A s, G a$
The value of electronegativity (EN) increases along a period towards right and decreases down the group. However, it is least of inert gases as they have stable configuration . Considering these factors, the correct order is in option A. i.e., $B r - A s - G a .$
