Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.796\% 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(NCCN1CCCC1)C1CC(=O)N(C2CCCCC2)C1
b) COc1ccc2c(c1)N(C)/C(=C1/SC(=S)N(NC(C)=O)C1=O)S2
c) CC(NCC(=O)Nc1ccccc1C(=O)NC1CC1)c1ccc(S(C)(=O)=O)cc1
Answer: a. O=C(NCCN1CCCC1)C1CC(=O)N(C2CCCCC2)C1
