Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.428\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COc1cccc(NC(=O)CCNC(=O)Cn2ccc3ccccc3c2=O)c1
b: O=C(CCn1c(=O)c2cccn2c2ccc(F)cc21)NCCc1ccccc1
Answer: b. O=C(CCn1c(=O)c2cccn2c2ccc(F)cc21)NCCc1ccccc1
