1. The given conditional statement is: "If two lines in a plane are perpendicular to the same line, then the lines are parallel." 2. The inverse of a conditional statement "If P, then Q" is "If not P, then not Q." 3. Here, - P: Two lines in a plane are perpendicular to the same line. - Q: The lines are parallel. 4. The inverse is: "If two lines in a plane are not perpendicular to the same line, then the lines are not parallel." 5. Comparing with the options, this matches option A. **Final answer:** A) If two lines in a plane are not perpendicular to the same line, then the lines are not parallel.
