Task: Answer the multiple-choice question.
Question: Which compound exhibits a 12.842\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C1CC(N2CCN(c3ccccc3)CC2)C(=O)N1CCc1ccccc1
b: O=C(N/C(=C\c1ccco1)C(=O)N1CCCC1)c1cccs1
c: CN(C(=O)c1c[nH]c(=O)cc1C(F)(F)F)c1ccc(Cl)cc1
d: C=CCSc1nc(-c2ccccc2)c2cc(Cl)ccc2n1
Answer: d. C=CCSc1nc(-c2ccccc2)c2cc(Cl)ccc2n1
