Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.898\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccccc1NNC(=O)C(O)(c1ccccc1OC)c1ccccc1OC
b: CCCCc1nc2ccc(S(=O)(=O)O)cc2[nH]1
c: CCCCC(=O)Nc1ccccc1C(=O)N1CCOCC1
d: O=C(COc1ccc(F)cc1Cl)Nc1ccc(N2CCOCC2)cc1N1CCOCC1
Answer: a. COc1ccccc1NNC(=O)C(O)(c1ccccc1OC)c1ccccc1OC
