I keep getting “Reflex arc” questions wrong in Neural Control and Coordination. What's the trap?

thinking the brain processes and decides a reflex.

The usual trap: thinking the brain processes and decides a reflex. How to avoid it: a reflex is a spinal shortcut; the brain is informed only afterwards. Go back to the definition — a rapid pathway -- receptor, sensory neuron, spinal cord, motor neuron, effector -- that acts without waiting for the brain.
