Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.934\% 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 additional words.
Options:
a COc1cc(C2CC(=O)N3CN(Cc4ccco4)CSC3=C2C#N)ccc1OCc1ccccc1
b NC(=O)COC(=O)/C=C/c1ccccc1[N+](=O)[O-]
c C1CCCCCC2(CCCCC1)OCC(CN1CCOCC1)O2
d COc1ccccc1-c1n[nH]c(=S)n1-c1ccccc1
Answer: b. NC(=O)COC(=O)/C=C/c1ccccc1[N+](=O)[O-]
