Which substance fits the following description?
a) A substance that partially activates trace amine-associated receptors (TAAR1), leading to increased cAMP levels and inhibition of serotonin, dopamine, and norepinephrine transporters, subsequently affecting the reuptake and metabolism of catecholamines.
b) A substance that is a full agonist of trace amine-associated receptors (TAAR1), leading to increased cAMP levels and inhibition of serotonin, dopamine, and norepinephrine transporters, subsequently affecting the reuptake and metabolism of catecholamines.
c) A substance that antagonizes trace amine-associated receptors (TAAR1), leading to decreased cAMP levels and inhibition of serotonin, dopamine, and norepinephrine transporters, subsequently affecting the reuptake and metabolism of catecholamines.
d) A substance that has no effect on trace amine-associated receptors (TAAR1), leading to decreased cAMP levels and inhibition of serotonin, dopamine, and norepinephrine transporters, subsequently affecting the reuptake and metabolism of catecholamines.
