Answer: Choice D
The general format for a conditional is "If P, then Q". The P and Q are placeholders for phrases or expressions. Think of them as empty boxes and inside the boxes you'll place words or a sentence (or sometimes math symbols as well). To form the converse of that template, we simply swap P and Q to get "If Q, then P". In our case,
P = point is in the fourth quadrant
Q = coordinates are negative
so that's how we end up with the answer "If the coordinates of a point are negative, then the point is in the fourth quadrant"
