Task: Answer the multiple choice question.
Question: Which compound has a 4.092\% 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 C/C(=N\NC(=O)c1ccc(OC2CCCC2)cc1)c1ccc(O)cc1
b CN(C(=O)N1CCN(S(=O)(=O)c2ccccc2)CC1)c1ccccc1
c O=c1[nH]c(=O)n(CCC2=CCCCC2)c(O)c1C=NCCN1CCNCC1
Answer: b. CN(C(=O)N1CCN(S(=O)(=O)c2ccccc2)CC1)c1ccccc1
