Task: Answer the multiple choice question.
Query: Which compound exhibits a 10.663\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=c1[nH]cc(COCC(F)(F)C(F)(F)C(F)(F)F)c(=O)[nH]1
b. COc1cc(S(=O)(=O)NCc2ccncc2)ccc1Br
Answer: a. O=c1[nH]cc(COCC(F)(F)C(F)(F)C(F)(F)F)c(=O)[nH]1
