Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.658\% 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) Cc1ccc(NC(=O)CN(C)C(=O)Cc2c(Cl)cccc2Cl)cc1
(b) O=C(CCNC(=O)c1ccc(Cl)cc1)Nc1ccc(S(=O)(=O)N2CCCCC2)cc1
Answer: b. O=C(CCNC(=O)c1ccc(Cl)cc1)Nc1ccc(S(=O)(=O)N2CCCCC2)cc1
