Correct Answer - Option 1 : (1, 1)

Concept:

Let A(x1, y1) and B(x2, y2) be the two points then the mid-point of the line joining the points A and B is $\rm (\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}).$

Calculation:

Given: C(3, - 4) and D(- 1, 6)

As we know that, the mid-point of the line joining the points A(x1, y1) and B(x2, y2) is given by $\rm (\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}).$

Let R be the mid-point between the points C and D.

$\Rightarrow \rm R=(\frac{3-1}{2}, \frac{-4+6}{2} )=(1, 1)$

Hence, the correct option is 1.
