Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.486\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(Cn1nnc(-c2ccccc2Cl)n1)N1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
b) CCCCN(C(=O)NC(=O)NC12CC3CC(CC(C3)C1)C2)S(C)(=O)=O
c) CCN(CC)Cc1ccccc1Sc1ccccc1.O=C(O)/C=C\C(=O)O
Answer: a. O=C(Cn1nnc(-c2ccccc2Cl)n1)N1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
