Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.546\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COCCNC(=O)CCn1nc(-c2ccc(Cl)cc2)c2ccccc2c1=O
b: O=C(Cc1ccccc1[N+](=O)[O-])Nc1nccs1
c: O=C(CC1C(=O)NCCN1Cc1ccccc1C(F)(F)F)NC1CCCC1
d: O=S1(=O)[C@H]2C[C@@H]3C=C[C@@]2(CN1Cc1ccc(F)cc1)O3
e: CO/N=C(/C)CCS(=O)(=O)c1ccccc1
Answer: c. O=C(CC1C(=O)NCCN1Cc1ccccc1C(F)(F)F)NC1CCCC1
