Solution

The correct option is B Weak bonds
The correct option is A.
The presynaptic neuron releases a chemical (i.e., a neurotransmitter) that is received by the postsynaptic neuron's specialized proteins called neurotransmitter receptors. The neurotransmitter molecules bind to the receptor proteins and alter postsynaptic neuronal function. These signals are generally weak as they are not ionic.
