Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 11.817\% 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 additional words.
Options:
a: COc1ccc(NC(=O)Cn2c3ccccc3c3nc4n(c(=O)c32)CCS4)cc1OC
b: O=C(COc1ccc(-n2cnnn2)cc1)Nc1ccccc1OC(F)F
Answer: b. O=C(COc1ccc(-n2cnnn2)cc1)Nc1ccccc1OC(F)F
