Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 19.292\% human ether-à-go-go related gene (hERG) inhibition at 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(NC1CCCN(Cc2ccccc2F)C1)C1CCC1
b. O=C(O)c1ccc2c(c1)OCCO2
c. Nc1no[n+]([O-])c1-c1ccccc1
d. Cn1c(=O)c2[nH]c(CN(Cc3ccccc3)Cc3ccccc3)nc2n(C)c1=O
Answer: c. Nc1no[n+]([O-])c1-c1ccccc1
