Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.909% 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. COc1ccc(CN2CCN(C(=O)CN3C(=O)C4C5C=CC(C5)C4C3=O)CC2)c(OC)c1OC
b. CCCCCCCSc1cc(OC)c(CCN(C)C)cc1OC.O=C(O)/C=C\C(=O)O
Answer: a. COc1ccc(CN2CCN(C(=O)CN3C(=O)C4C5C=CC(C5)C4C3=O)CC2)c(OC)c1OC
