Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 14.111\% 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) CC(/C=C1\NC(=S)NC1=O)=C\c1ccccc1
b) CCN(c1ccccc1)S(=O)(=O)c1ccc2c(c1)CCCN2C(C)=O
c) CC(C)Nc1c([N+](=O)[O-])c(=O)oc2ccccc12
d) CC(C)Oc1ccc(C(=O)Nc2nc3ccccc3[nH]2)cc1
Answer: c. CC(C)Nc1c([N+](=O)[O-])c(=O)oc2ccccc12
