B) Chemically gated sodium channels will be closed.
C) Chemically gated sodium channels will open.
D) Chemically gated chloride channels will open.

When a neurotransmitter acts in an excitatory manner, it is trying to cause an action potential in the postsynaptic cell. Opening chemically gated sodium channels will cause an influx of positive ions into the cell, making it more likely to reach its threshold for firing an action potential.
