Task: Answer the multiple choice question.
Question: Which drug exhibits a -12.284\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COC(=O)C(Cc1cnc(Cl)s1)(C(=O)OC)c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
[b] Cc1ccc2nc(SCC(=O)N(C)C3CCS(=O)(=O)C3)[nH]c2c1
[c] CC(=O)Nc1cc(S(=O)(=O)Nc2ccccc2)c(C)cc1C
[d] COc1ccc(-c2csc(N(CCCN(C)C)C(=O)c3ccc(C)cc3)n2)cc1.Cl
Answer: a. COC(=O)C(Cc1cnc(Cl)s1)(C(=O)OC)c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
