Correct Answer - Option 4 : (-7/2, -2)

__Concept__:

Midpoint of line segment joining (x_{1}, y_{1}) and (x_{1}, x_{2}) is = [(x_{1} + x_{2})/2, (y_{1} + y_{2})/2]

__Calculation__:

Given: The two points of a line are (-2, -1) and (-5, -3)

The midpoint of the line segment joining (-2, -1) and (-5, -3)

⇒ [(-2 – 5)/2, (-1 – 3)/2] = (-7/2, -2)
