Task: Answer the multiple choice question.
Question: Which compound has a 9.389\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1cccc(N(CC(=O)N2CCOCC2)S(C)(=O)=O)c1
b: COC(=O)CNC(=O)CCc1nnc(C2(c3ccc(Cl)cc3)CCC2)o1
c: COc1cc2ccccc2cc1C(=O)NNC(=O)c1ccccc1O
d: Cc1ccccc1C(=O)Nc1ccc(C(=O)N/N=C/c2ccc(F)cc2)cc1
Answer: c. COc1cc2ccccc2cc1C(=O)NNC(=O)c1ccccc1O
