Problem statement: Answer the multiple-choice question.
Question: Which compound has a 13.087\% 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, or c without using any other words.
Options:
a NC(N)=O
b O=C1NC[C@H](c2ccccc2)N(CC2CCCCC2)C1=O
c Cc1nn(CC(=O)NCc2ccc(-n3cccn3)cc2)c(C)c1[N+](=O)[O-]
Answer: b. O=C1NC[C@H](c2ccccc2)N(CC2CCCCC2)C1=O
