Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.818% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CCOC(=O)c1c(C)n(C(C)C)c2ccc(OC)cc12
(b) Cc1ccccc1OCCNc1cc(N2CCN(CCO)CC2)ccc1[N+](=O)[O-]
(c) COc1cccc(N2CCN(C(=O)c3c(C)nn(-c4ccccc4)c3C)CC2)c1
(d) C#CCOCCOCCOCCNc1nc(N2CCN(C(=O)[C@H](CCC(=O)O)n3cc(C(N)CC(C)C)nn3)CC2)nc(N2CCN(C(=O)[C@H](Cc3ccc(O)cc3)n3cc(C(N)[C@H](C)CC)nn3)CC2)n1.Cl
(e) CCOC(=O)C1=C(C)N(c2ccccc2)C(=O)/C1=C\c1ccc(O)c(OC)c1
Answer: e. CCOC(=O)C1=C(C)N(c2ccccc2)C(=O)/C1=C\c1ccc(O)c(OC)c1
