Best answer
The correct option is (b) SNAREs

Best explanation: SNAREs present on the membranes of synaptic vesicles and presynaptic membranes are the only targets of potent bacterial toxins; botulism and tetanus. Cleavage of SNAREs by these toxins blocks the release of neurotransmitters and lead to paralysis.
