Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.563\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C1Nc2ccccc2C1c1ncc(C(F)(F)F)cc1Cl
b. COc1ccc(N2C(=O)CC(c3ccc(OC(C)C)cc3)C2=O)cc1
c. C=C(C)C(=O)Nc1cccc(C2=NOC3(C2)C[C@@H](C(N)=O)N(C(=O)C(=C)C)C3)c1
Answer: a. O=C1Nc2ccccc2C1c1ncc(C(F)(F)F)cc1Cl
