Task: Answer the multiple choice question.
Question: Which drug exhibits a -19.978% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) NC(=O)c1ccc(NC(=O)CCCN2C(=O)NC3(CCCC3)C2=O)cc1
(b) Cc1nc(CS(=O)c2ccc(Cl)cc2)cc(NCc2ccc(Cl)cc2Cl)n1
Answer: b. Cc1nc(CS(=O)c2ccc(Cl)cc2)cc(NCc2ccc(Cl)cc2Cl)n1
