Task: Answer the multiple choice question.
Question: Which drug has a 17.721\% 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 COc1cccc(/C(C)=N/NC(=O)Cc2c(C)[nH][nH]c2=O)c1
b O=C(Nc1ccccc1)N1CCc2ccccc2C1
Answer: b. O=C(Nc1ccccc1)N1CCc2ccccc2C1
