Explanation:
- <em>Presynaptic mechanism:</em> one way to modify the synaptic transmission before it happens is affecting transmitters release, one example is calcium channel blockers (for example, verapamil), this action won't allow transmitters out, therefore, there won't be a synaptic transmission.
- <em>Postsynaptic mechanism:</em> one method to modify synaptic transmission after it happens is blocking the transmitter receptors, one example of this is antipsychotic drugs that block dopamine receptors.
I added some images with another examples for both cases. I hope you find this information interesting! Good luck!

Answer:
Positive feedback
Explanation:
The homeostasis of the body is generally maintained by the feedback mechanism of the body. Two main types of feedback mechanism are positive feedback and negative feedback mechanism.
Positive feedback mechanism may be defined as in which the final product of the reaction or hormone increase the further secretion of that particular hormone. The positive feedback mechanism can exaggerates the effect of the variation from the normal condition of the body.
Thus, the correct answer is option (e).
