Task: Answer the MCQ question.
Question: Which drug has a -0.326\% 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, d, or e without using any additional words.
Options:
(a) CNC(=S)N1N=C(c2ccccc2)CC1c1ccccc1Cl
(b) Cc1ccc(SCC(=O)NCCN2C(=O)CSC2=O)c(C)c1
(c) O=C(CN(CCc1ccccc1)C(=O)Cn1nnc(-c2cccs2)n1)NCc1ccco1
(d) COc1ccccc1C(CNc1ncccc1[N+](=O)[O-])N(C)C
(e) Cc1oc(=O)c(NC(=O)c2ccccc2)cc1C(C)O
