Task: Answer the multiple choice question.
Question: Which compound exhibits a 18.608\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) COc1c(C)cc(S(=O)(=O)NC2CC(C)(C)NC(C)(C)C2)c(C)c1C
b) Cl.O=C(CCl)N1CCN(CC(=O)N2CCCC2)CC1
c) O=C(CN1C(=O)/C(=C/c2cccc(Cl)c2)SC1=S)NC1C=CS(=O)(=O)C1
Answer: b. Cl.O=C(CCl)N1CCN(CC(=O)N2CCCC2)CC1
