Task: Answer the multiple-choice question.
Query: Which drug exhibits a -3.620\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(O)CCNS(=O)(=O)c1ccc(Oc2ccccc2Cl)cc1
b CCC1=NN(C(=O)c2ccc(Br)cc2)C(O)(c2ccccc2)C1
c COc1ccccc1CNC(=O)CNC(=O)Cn1cnc2ccccc2c1=O
Answer: a. O=C(O)CCNS(=O)(=O)c1ccc(Oc2ccccc2Cl)cc1
