Answer:
The true statements are-
1) Sensory neurons transmit efferent impulses towards the antagonist muscles
2) Sensory neurons transmit afferent impulses towards the spinal cord (CNS)
3)When a stretch activates the muscle spindle, these sensory neurons transmit impulses at a higher frequency.
A basic principle in science is that any law, theory, or otherwise can be disproven if new facts or evidence are presented. If it cannot be somehow disproven by an experiment, then it is not scientific. Take, for example, the Universal Law of Gravitation
