Task: Answer the multiple choice question.
Question: Which compound has a 1.536% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CC(=O)Oc1cc(OC(C)=O)c2c(=O)c(-c3ccc4c(c3)OCCCO4)c(C)oc2c1
b O=C(COC(=O)c1cccnc1)c1ccc(Cl)c(Cl)c1
Answer: b. O=C(COC(=O)c1cccnc1)c1ccc(Cl)c(Cl)c1
