Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.884% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCS(=O)(=O)Nc1ccc(-c2ccc(NS(=O)(=O)CC)c(OC)c2)cc1OC
(b) COC(=O)c1cccc(-n2c(=O)n(Cc3ccccc3)c(=O)c3[nH]cnc32)c1C
Answer: a. CCS(=O)(=O)Nc1ccc(-c2ccc(NS(=O)(=O)CC)c(OC)c2)cc1OC
