Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.521\% 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: CC(NC(=O)C(=O)NCCc1c[nH]c2ccccc12)c1ccccc1
b: Cc1cccc(NC(=S)N(CCN(C)C)C(C)c2ccccn2)c1
c: CN1CCc2nc(NC(=O)c3cccc(OC(F)F)c3)sc2C1
d: CC(CN1CCCCC1)OC(=O)COc1ccc(Br)cc1
e: O=C(CCc1nnc2n(Cc3ccc(F)cc3)c(=O)c3ccccc3n12)N1CCN(c2ccccn2)CC1
Answer: c. CN1CCc2nc(NC(=O)c3cccc(OC(F)F)c3)sc2C1
