Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.665\% 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 other words.
Options:
(a) CCNC(=O)COC(=O)c1cccc(Br)c1
(b) NC(=O)[C@@H]1CCCN1Cc1nc(-c2ccccc2)no1
(c) COc1ccc(Br)cc1C(=O)NC(=S)Nc1c(C)n(C)n(-c2ccccc2)c1=O
(d) Cc1c(OCc2nn[nH]n2)ccc2c3c(c(=O)oc12)CCC(C)C3
(e) COc1ccccc1N=Nc1ccc(O)c2ncccc12
Answer: b. NC(=O)[C@@H]1CCCN1Cc1nc(-c2ccccc2)no1
