Answer: C
Explanation:
The height of the parallelogram for A is 3 units while the length the base is 6 units.
For D it follows this same pattern, the height is 1 which is half of the length of the base, 2.
B also follows this pattern, the height is 2 which is half of the length of the base, 4
C does not follow this pattern and is the odd one out.
