Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.201\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a Cc1c(C)c2ccc(OCC(=O)N3CCC(C(=O)O)(c4ccccc4)CC3)c(C)c2oc1=O
b CC(=O)N(CCN(C(C)=O)c1ccccc1)c1ccccc1
Answer: b. CC(=O)N(CCN(C(C)=O)c1ccccc1)c1ccccc1
