The answer would be: <span>Binary fission involves a single parent cell, so there is only one set of genetic information that can be duplicated and passed on to the daughter cells.
If you see the picture, it is clear that there is only 1 parent involved in binary fission. This will exclude the first and third option. 
The genetic duplicated before splitting, so the cells should have an equal number of parent genetic material, not halves. This will exclude the second option.

The correct answer is: prevent reception of a signal in a receiving neuron
Neurotransmitters are signal molecules or chemical messengers which transmit signals across a chemical synapse. Neurotransmitters send the signal, from one neuron (nerve cell) to another neuron, from neuron to muscle cell (motor plate), or from neuron to gland cell.
Drugs that bind to neurotransmitter’s receptor can have two effects on its action:
•	Antagonists-they bind to receptor and thus prevent a neurotransmitter from binding to it
•	Agonists-they bind to receptor and mimic the normal neurotransmitter (have the same effect as neurotransmitter).
