Answer: The correct option is (B) 
Step-by-step explanation: We are given to find the length of the segment whose endpoints are A(-4, 3) and B (10, 6).
We know that
the length of a line segment with endpoints (a, b) and (c, d) is calculated using distance formula as follows :

Therefore, using distance formula, the distance between the endpoints A(-4, 3) and B (10, 6) is given by

Thus, the length of the line segment AB is 
Option (B) is CORRECT.
