Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 0.723\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccc(CCC(C)N2CCc3ccccc3C2)cc1
b: Cc1cc2oc(=O)cc(CN3CCN(Cc4ccc5c(c4)OCO5)CC3)c2cc1C
c: C=CCn1c(O)c(C(CC)=Nc2ccc(N(C)C)cc2)c(=O)[nH]c1=O
Answer: b. Cc1cc2oc(=O)cc(CN3CCN(Cc4ccc5c(c4)OCO5)CC3)c2cc1C
