Task: Answer the multiple choice question.
Question: Which compound exhibits a -21.599% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCOc1ccc(NC(=S)NS(=O)(=O)c2cc(Br)ccc2OCC)cc1
b. CCCCN(C)CCCN1C(=O)C2C(C(=O)Nc3cccc(OC)c3)C3C=CC2(O3)C1C(=O)NC1CCCCC1C
c. COc1ccc(CC(=O)Oc2ccc(F)c(F)c2)cc1S(=O)(=O)N1CCOCC1
d. CC(C)(C)NC(=O)Cc1ccc(S(=O)(=O)N2CCCC2)s1
Answer: b. CCCCN(C)CCCN1C(=O)C2C(C(=O)Nc3cccc(OC)c3)C3C=CC2(O3)C1C(=O)NC1CCCCC1C
