I AM CONFUSED

Reflex arcs are formed in the spinal cord, although the information inputs also reach the brain. The purpose of reflex action is to provide quick response in situations where the organism does not have enough time to think. For example if we touch a hot object, by the time brain will process this information and respond, our hand would have already get burnt.

Sending the information to the brain ensures that the brain is aware of what has happened and will store it in its memory.
