Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -6.940\% 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) COc1ccc(N(C)S(=O)(=O)c2c(C)[nH]c(=O)[nH]c2=O)cc1
(b) CCCc1cc(=O)oc2cc(OCC(=O)Nc3cc(C)on3)ccc12
Answer: a. COc1ccc(N(C)S(=O)(=O)c2c(C)[nH]c(=O)[nH]c2=O)cc1
