The arrow represents the vector R. Which diagram does not represent R as two perpendicular components?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

A[Diagram A: Vector R pointing up-right, with horizontal right and vertical up components forming a right angle and summing to R.]

B[Diagram B: Vector R pointing up-right, with horizontal right and vertical up components forming a right angle and summing to R.]

C[Diagram C: Vector R pointing up-right, with two perpendicular components pointing downwards and to the left/right, which do not sum to R.]

D[Diagram D: Vector R pointing up-right, with horizontal right and vertical up components forming a right angle and summing to R.]

✓ Correct answer

C: [Diagram C: Vector R pointing up-right, with two perpendicular components pointing downwards and to the left/right, which do not sum to R.]
