Task: Answer the multiple choice question.
Query: Which compound has a 8.593\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. COc1cccc(-n2cc(C(=O)O)c3ccccc3c2=O)c1
b. O=C(c1cccc(S(=O)(=O)N2CCOCC2)c1)N(Cc1ccco1)Cc1cccs1
c. Cn1cnc2c1c(=O)n(Cc1c(Cl)cccc1Cl)c(=O)n2C
Answer: a. COc1cccc(-n2cc(C(=O)O)c3ccccc3c2=O)c1
