Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -3.352\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1cc(Oc2ccccc2)nc(-c2ccccc2O)n1
b: O=C(CSc1nc2ccc(Cl)cc2[nH]1)NCCc1ccc(Cl)cc1
c: CCOC(=O)Cc1csc2nc(-c3ccccc3)nn12
d: COC(=O)[C@@H]1C[C@]2(OC(=O)c3ccccc3)C=CC(=O)C[C@@H]2N1C(=O)OCc1ccccc1
Answer: a. Cc1cc(Oc2ccccc2)nc(-c2ccccc2O)n1
