Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.651\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: C(/C=C/c1ccccc1)=N/N1CCN(c2ccccc2)CC1
b: COC(=O)c1ccc2ccn(CC(=O)NC3CCCCC3)c2c1
c: O=C(CCn1cccc1)N1CCc2ccccc21
Answer: b. COC(=O)c1ccc2ccn(CC(=O)NC3CCCCC3)c2c1
