Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.350\% 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=C(O)[C@H](Cc1ccccc1)NC(=O)N1CCOCC1
(b) Cc1cnn(-c2cc(N/N=C/c3ccccc3Cl)ncn2)c1
(c) CC1=Nc2ccc(Br)cc2C(c2ccccc2)N1CC(=O)O
(d) CCOC(=O)Cn1nc(C)c(NC(=O)c2ccc(Br)o2)c1C
(e) CN1OCC2Cn3c(nc4ccccc43)C21
Answer: e. CN1OCC2Cn3c(nc4ccccc43)C21
