Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.922\% 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 additional words.
Options:
a: NNC(=O)C(Cc1cnc[nH]1)NC(=O)OCc1ccccc1
b: CC(Sc1nnc(-c2ccc(Cl)cc2)n1C)C(N)=O
c: O=C(CN1C(=O)c2cccc3cccc1c23)Nc1ccccc1
d: O=C(CN(C1CCCCC1)S(=O)(=O)c1ccc(F)cc1)Nc1ccc2c(c1)OCO2
Answer: c. O=C(CN1C(=O)c2cccc3cccc1c23)Nc1ccccc1
