Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.537\% 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 additional words.
Options:
a.) CC(C)=Cc1oc2ccc([N+](=O)[O-])cc2c1N1CC(C)OC(C)C1
b.) O=C(Nc1ccc2c(c1)Cc1ccccc1-2)c1ccco1
Answer: b. O=C(Nc1ccc2c(c1)Cc1ccccc1-2)c1ccco1
