Loud sound: The prolonged or long exposure towards the loud sound may cause the tinnitus condition.
Benign tumor: The development of benign tumor in ear is rare. This tumor can also cause the tinnitus in an individual ear.

Answer:
The answer to the question: Where does the stimulus occur in order to initiate an AP, would be, B: Dendrites.
Explanation:
When an impulse is to be generated and passed on as an action potential towards a corresponding neuronal cell, and a final affected organ, the neurons need first to be stimulated so that an action potential begins. This stimulus comes as a neurotransmitter released by other neurons near the one that will be stimulated. This neurotransmitter will bind to the receptors on the dendrites of the neuron to be stimulated and immediately this will cause the ion channels, gated and non-gated, to open and close so that an action potential can be initiated. The cell body then initiates the first action potential, and will in turn stimulate the axon to also start their own action potential, which will, like a domino effect, move down to the axon terminals. This process will be followed all along a neuronal circuit.
