Correct option is (D) IV
Given that (a, 2) lies in II quadrant.
We know that any point which has x-coordinate negative and y-coordinate positive will lie in II quadrant.
\(\therefore\) If (a, 2) lies in II quadrant.
Then a < 0
\(\Rightarrow-a>0\)
Since, \(-a>0\;\&\;-2<0\)
\(\therefore\) (-a, -2) lies in IV quadrant.
(If x-coordinate is positive & y-coordinate is negative then that point lies in IV quadrant)
