d.The receiving neuron is less likely to generate an action potential

Explanation:

If a signal from a sending neuron makes the receiving neuron more negative inside the receiving neuron is less likely to generate an action potential. The reason for this is that initially the cell has a -90 mv charge, for a potential action to happen the charge has to raise up to 40mv. If the signal that the neuron receives  makes the inside of the cell more negative  the charge will continue being negative and will not increase to generate the potential action.
