Task: Answer the multiple-choice question.
Question: Which drug exhibits a -4.004\% 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: CCCCCCCCOC(=O)c1nc(Cl)c(Cl)c(N)c1Cl
b: COC(=O)N=Nc1c(O)n(Cc2ccccc2)c2ccccc12
c: O=C(N/N=C/c1ccc(O)cc1)/C(=C/c1ccccc1)CCO
d: COc1cccc(C(=O)NCC(=O)N/N=C/c2cccc(OC(=O)c3ccc([N+](=O)[O-])cc3)c2)c1
e: CC1CCN(Cc2nc(-c3ccccc3)no2)CC1.Cl
Answer: c. O=C(N/N=C/c1ccc(O)cc1)/C(=C/c1ccccc1)CCO
