Task: Answer the multiple choice question.
Query: Which drug has a -3.976\% 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) C=C(C)C1CCC2(C(=O)O)CCC3(C)C(CCC4C5(C)C(C=O)C(O)C(C)(C)C5CCC43C)C12
(b) COC(=O)c1cc(=O)n2c(-c3ccccc3)csc2n1
(c) CCCCC1=CC2=C(c3ccco3)C(=O)C(C)(OC(=O)c3ccc(OC)cc3)C(=O)C2=CN1c1ccc(OC)cc1
Answer: b. COC(=O)c1cc(=O)n2c(-c3ccccc3)csc2n1
