Select the Mechanism of Action of Trimethadione (Tridione) and the Oxazolidinedione

Select the mechanism of action of trimethadione (Tridione) and the oxazolidinedione class of drug agents.

A) Trimethadione (Tridione) reduces the T-type calcium currents in the thalamus, which reduces the occurrence of seizures.
B) Trimethadione (Tridione) attaches to plasma protein, causing a reduction in the occurrence of seizures.
C) Trimethadione (Tridione) increases the inhibitory effects of the neurotransmitter gamma-aminobutyric acid (GABA) . In the brain, this suppresses the excitability of epileptogenic neurons and makes them less likely to discharge and initiate a seizure.
D) None of these are correct.
