Task: Answer the multiple-choice question.
Question: Which drug has a 3.848\% 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 additional words.
Options:
a: CCOC(=O)N1CCC(Nc2cc(C)nc3c(-c4ccccc4OC)c(C)nn23)CC1
b: O=C1CC(C(F)(F)C(F)(F)C(F)(F)C(F)F)=Nc2ccccc2N1
c: CN1CCN(/N=C/c2ccc(-c3ccccc3)cc2)CC1
d: CC(C)(C)OC(=O)N1CSC[C@H]1C(=O)NC[C@H](CC(=O)O)c1ccc(Cl)cc1
e: Cc1ccc(C2(C)NC(=O)N(Cc3c(C)noc3C)C2=O)cc1
Answer: c. CN1CCN(/N=C/c2ccc(-c3ccccc3)cc2)CC1
