Answer:- B. Group 5A, period 3.
Explanations:- From the given electron configuration the element has 5 electrons in outer most shell. It tells us the element is present in group 5A.
Value of principal quantum number is three which is the number written in front of s and p in the electron configuration and it tells us about the period number. The number is 3 means element is present in period 3.
So, the right answer is, B. group 5A, period 3.
