Answer:
Reflexive action controlled by the brain ----- Blinking your eyes.
This is a reflex, yes, but with a little bit of concentration, you can control it.

Reflexive action ---- Jumping when startled by a loud horn.
The loud horn scares you, then your reflexes made you jump. (if you know there will be a loud sound, you could control the reflexes, but let's suppose you don't know it)
Voluntary action ----- Bicycling on the road.
You need to actually think every movement you do here, you maybe can use some muscle memory, but not reflexes in principle.
