Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.346\% 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) CCN(CC)CCNC(=O)/C(=C/c1cn(CC)c2ccccc12)NC(=O)c1cc(OC)c(OC)c(OC)c1
(b) CCn1c(Cc2cccs2)nnc1SCC(=O)NC(C)(C)C
(c) O=C(Cc1cn(Cc2cccc(Cl)c2)c2ccccc12)N1CCCCCC1
(d) CCC(C(=O)Nc1c[nH]c(=O)[nH]c1=O)c1ccccc1
(e) COc1ccccc1-n1nc(C)c(-c2ccccc2)c1N
Answer: b. CCn1c(Cc2cccs2)nnc1SCC(=O)NC(C)(C)C
