Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.694\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C(Cc1c(F)cccc1Cl)Nc1ccccc1N1CCCCC1
b. O=C(NCc1cccs1)c1cc(S(=O)(=O)N2CCCCC2)ccc1Cl
c. O=C(CCNc1ccc(Cc2ccncc2)cc1)c1ccc([N+](=O)[O-])cc1
Answer: c. O=C(CCNc1ccc(Cc2ccncc2)cc1)c1ccc([N+](=O)[O-])cc1
