Answer:
(A)If lines have negative reciprocal slopes, then they are perpendicular.
Step-by-step explanation:
The given statement is:
Perpendicular lines have negative reciprocal slopes.
To get the converse of the conditional statement, interchange the hypothesis and the conclusion.
Then the converse of the above given statement will be given as:
If the lines have negative reciprocal slopes, then they are perpendicular.
Hence, option A is correct.
