Task: Answer the multiple choice question.
Query: Which drug has a 15.516\% 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) Cc1cc(NS(=O)(=O)c2ccc(NC(=O)CSc3nc4ncc(Cl)cc4[nH]3)cc2)nc(C)n1
(b) O=C1C(Cl)=C(N2CCCCCC2)C(=O)N1c1ccc(Cl)cc1
Answer: b. O=C1C(Cl)=C(N2CCCCCC2)C(=O)N1c1ccc(Cl)cc1
