Problem statement: Answer the multiple choice question.
Question: Which drug has a 2.619\% 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 additional words.
Options:
[a] NS(=O)(=O)c1cc(Cl)c(Cl)c(S(N)(=O)=O)c1
[b] O=C(COC(=O)C1CCCCC1)Nc1ccc([N+](=O)[O-])cc1
[c] CC(=O)NC(c1ccco1)c1cc(F)c2cccnc2c1O
[d] CCn1c(SCC(=O)Nc2cccc(NC(=O)c3cccs3)c2)nnc1-c1ccncc1
Answer: b. O=C(COC(=O)C1CCCCC1)Nc1ccc([N+](=O)[O-])cc1
