\(C\)

Show Worked Solution

Consider Option C:  Sensory input → Processing → Motor response

The correct sequence involves receiving sensory information (seeing the ball), processing in the central nervous system, then sending motor signals to muscles.

Other Options:

  • A is incorrect: Incorrect sequence – Output cannot occur before processing
  • B is incorrect: Processing cannot occur before receiving sensory input
  • D is incorrect: Processing must occur between input and output for coordinated movement

\(\Rightarrow C\)
