Animal hiding-holding still response follows the reflex arc sequence. The fourth event in the series is option B) signaling by efferent PNS neurons.
When the animal receives the stimuli, it responds to them. In the case of hiding-holding still response, the animal might freeze due to motor inhibition that reduces excitatory signals.
The reception and reaction to stimuli follows the reflex arc sequence.
The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.
The correct answer is B) signaling by an efferent PNS neurons.
