Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.851\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=C(COC(=O)/C=C/c1ccc(OC(F)F)cc1)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
(b) C=CCN1CN(S(=O)(=O)c2ccc(OC)cc2)c2nc3ccccc3nc21
Answer: a. O=C(COC(=O)/C=C/c1ccc(OC(F)F)cc1)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
