Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.983% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] Cc1cc2c(c(=O)o1)C(C1C=CCCC1)C(C#N)=C(N)O2
[b] CCc1cc(=O)oc2c(C)c(O)c(CN(C)C)cc12
Answer: b. CCc1cc(=O)oc2c(C)c(O)c(CN(C)C)cc12
