Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 8.505\% 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=c1cc(O)c(-c2ccc(Cl)cc2)c(Cl)[nH]1
b. CN(C)C=O.COc1cc(/C=C/c2nc3ccccc3c(=O)n2-c2ccc(O)cc2)ccc1O
c. CC(=O)N/C(=C\c1ccccc1)C(=O)OCc1cccc(S(=O)(=O)N(C)C)c1
d. CCc1ccc(Oc2coc3cc(OC(=O)c4cc5ccccc5oc4=O)ccc3c2=O)cc1
Answer: a. O=c1cc(O)c(-c2ccc(Cl)cc2)c(Cl)[nH]1
