Problem statement: Answer the multiple choice question.
Query: Which compound has a 8.178\% 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=[N+]([O-])c1cc2c(cc1C=Nc1ccccc1)OCO2
[b] N#C/C(=C\c1ccc(-c2cccc([N+](=O)[O-])c2)o1)C(=O)N1CCOCC1
[c] COc1ccc(C2C3=C(CCCC3=O)Nc3nc(-c4cc(OC)c(OC)c(OC)c4)nn32)cc1OC
[d] Cc1cccc(C(=O)N2CCCC(N3CCN(c4ccc(F)cc4)CC3)C2)n1
Answer: b. N#C/C(=C\c1ccc(-c2cccc([N+](=O)[O-])c2)o1)C(=O)N1CCOCC1
