Task: Answer the multiple-choice question.
Query: Which compound exhibits a 14.081\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) CCCCC1C(=O)N(c2ccccc2)N(c2ccccc2)C1=O
b.) CCC1=C(OC(=O)N(CC)CC)N2C(=O)OC(=NCC3CC3)[C@]2(C)[C@H]2C1=CC[C@H]1C(=O)N(CC)C(=O)[C@H]12
c.) O=C(N/N=C\c1ccc(F)cc1)c1cc(OCC(F)(F)F)ccc1OCC(F)(F)F
Answer: a. CCCCC1C(=O)N(c2ccccc2)N(c2ccccc2)C1=O
