Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 8.021\% 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: O=C(COc1ccc(Br)cc1)Nc1ccccc1N1CCCC1
b: Brc1cccc(-c2cnc3n2CCCCC3)c1.Cl
c: O=C(Cc1ccccc1[N+](=O)[O-])OCC(=O)N1CCN(c2ccccc2)CC1
d: CC(=O)NC1CC2CCC(C1)N2
Answer: c. O=C(Cc1ccccc1[N+](=O)[O-])OCC(=O)N1CCN(c2ccccc2)CC1
