Task: Answer the multiple choice question.
Question: Which drug has a 13.107\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=C1C=C(c2ccccc2)C(O)(c2ccccc2)C1
(b) Nc1nc(Cn2nnc(-c3ccccc3Cl)n2)nc(N2CCOCC2)n1
(c) Cc1cc2c(cc1C)N(CC(=O)N1CCCC1)C(=O)CC(c1ccccc1)=N2
(d) CCNC(=O)COC(=O)CNC(=O)c1cc(Cl)cc([N+](=O)[O-])c1
(e) Cc1cc(C)c2c(-n3cccc3)c(NC(=O)OCc3ccccc3)sc2n1
Answer: a. O=C1C=C(c2ccccc2)C(O)(c2ccccc2)C1
