Geometry

Question Analysis:
This question checks your understanding of the conditions under which reflections produce rotations.

Key Concept Explanation:
For a transformation to result in a rotation, the two lines of reflection must intersect at some nonzero angle.

Step-by-Step Solution:
If two lines intersect at an angle, the composition of reflections produces a rotation.
If the lines are parallel or do not intersect, no rotation is produced.

Option Analysis:
D is correct because the lines must intersect at some angle for a rotation to occur.
