Task: Answer the multiple-choice question.
Query: Which drug exhibits a -0.605\% 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 other words.
Options:
(a) CCOC(=O)CSc1nc(N)c2c3c(sc2n1)CCCC3
(b) Cn1c(N2CCCC2)nc2c1c(=O)n(Cc1cccc(F)c1)c(=O)n2C
(c) O=C(CN1CCN(c2ccccn2)CC1)N(c1ccccc1)c1ccc2ccccc2c1
(d) COc1ccc(S(=O)(=O)N2CCCCCC2)cc1C(=O)OCC(=O)NC(N)=O
(e) CCc1cccc(CC)c1NC(=O)CSc1nnc(C(C)C)n1CC
Answer: a. CCOC(=O)CSc1nc(N)c2c3c(sc2n1)CCCC3
