1.	Which of these constitute a motor unit?(a) Motor neuron + muscle fibres(b) Motor neuron + fascia(c) Motor neuron + muscle(d) Motor neuron + muscle bundleI had been asked this question during an online interview.The origin of the question is Locomotion & Movement in division Locomotion and Movement of Biology – Class 11
