Task: Answer the multiple-choice question.
Question: Which drug exhibits a 0.415\% 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) O=C(c1noc2c1CCc1ccccc1-2)N1CCCc2ccccc21
b) NC(=O)COC(=O)/C=C/c1ccccc1[N+](=O)[O-]
Answer: a. O=C(c1noc2c1CCc1ccccc1-2)N1CCCc2ccccc21
