Task: Answer the multiple choice question.
Query: Which compound has a 16.191\% 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 other words.
Options:
a: O=c1c2ccccc2nc(/C=C/c2ccccc2)n1-c1ccccc1O
b: COc1ccc(C2CC(C(F)(F)F)n3ncc(C(=O)O)c3N2)cc1OC
c: COc1cccc(Sc2ccccc2/C=N/NC(N)=O)c1
Answer: a. O=c1c2ccccc2nc(/C=C/c2ccccc2)n1-c1ccccc1O
