Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.677\% 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)c1ccc2cc(C(N)=O)c(=O)oc2c1
(b) CN(CC(=O)Nc1ccc(F)c(F)c1F)C(=O)C1CSC2(C)CCC(=O)N12
(c) O=C(C1CCN(c2ncnc3c2nc2n3CCCCC2)CC1)N1CCN(c2ccccc2F)CC1
(d) O=c1[nH]c(=O)n(Cc2ccc(F)cc2)c(O)c1C=NCc1cccnc1
(e) CCN(CC)C(=O)c1[nH]cnc1C(=O)Nc1ccc(C)cc1
Answer: b. CN(CC(=O)Nc1ccc(F)c(F)c1F)C(=O)C1CSC2(C)CCC(=O)N12
