Task: Answer the multiple-choice question.
Query: Which compound exhibits a 6.449\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a Cc1ccc(CNC(=O)C2CCCN(c3nc(C)cc(C)n3)C2)cc1
b C=CCNC(=O)c1onc(CSc2ccc(F)cc2)c1C(=O)NCCOC
c O=c1c([N+](=O)[O-])cccn1Cc1ccc(F)cc1Cl
d CCCCN(C(=O)CN1C(=O)C2CC=CCC2C1=O)c1c(N)n(CCC)c(=O)[nH]c1=O
e NNC(=O)c1cccc(Cn2cc(Br)c([N+](=O)[O-])n2)c1
Answer: c. O=c1c([N+](=O)[O-])cccn1Cc1ccc(F)cc1Cl
