Adepolarizing synaptic potential is also known as a depolarizing synaptic potential is also known as an excitatory postsynaptic potential a hyperpolarizing postsynaptic potential an inhibitory postsynaptic potential an excitatory presynaptic potential

Postsynaptic potentials are changes in the membrane potential of postsynaptic terminal. A depolarizing synaptic potential is also known as an excitatory postsynaptic potential. it is the synaptic potential that makes postsynaptic neuron likely to fire an action potential. Postsynaptic neuron is of two forms excitatory and inhibitory.

Ithink that b is correct but just in case wait to see if someone else answers
