Dopamine, a type of neurotransmitter, is most likely to induce signal transmission by acting on the post synaptic membrane (Option B) of a neuron. Here's why:

1. Neurotransmitters like dopamine are chemicals that transmit signals across a synapse from one neuron (nerve cell) to another 'target' neuron, muscle cell, or gland cell.

2. The axon (Option A) is responsible for transmitting the electrical signal away from the neuron's cell body. However, dopamine doesn't act directly on the axon.

3. The nucleus (Option C) of a neuron contains the cell's genetic material, but it's not directly involved in signal transmission.

4. The axon hillock (Option D) is the part of the neuron where the electrical signal (action potential) is generated. But again, dopamine doesn't act directly on the axon hillock.

5. The post synaptic membrane (Option B), however, contains receptors that are specifically designed to receive and bind to neurotransmitters, including dopamine. When dopamine binds to these receptors, it causes changes in the receiving neuron, which leads to the transmission of the signal across the synapse.

So, dopamine is most likely to induce signal transmission by acting on the post synaptic membrane of a neuron.
