Problem statement: Answer the multiple choice question.
Question: Which compound has a 1.993% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] Cl.OCc1cc(CO)c(O)c(CCc2ccccc2)n1
[b] CC(NS(=O)(=O)c1cn(C)c(=O)n(C)c1=O)c1ccccc1
[c] COc1ccccc1N1CCN(CC(O)c2c(C)[nH]c3ccccc23)CC1
[d] O=C(Nc1ccccc1)c1cccc2c(Br)cccc12
[e] O=C(CSc1ccc(C(F)(F)F)cc1[N+](=O)[O-])Nc1ccc2ccccc2c1
Answer: e. O=C(CSc1ccc(C(F)(F)F)cc1[N+](=O)[O-])Nc1ccc2ccccc2c1
