Task: Answer the MCQ question.
Query: Which drug exhibits a -4.668\% 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: CCOc1ccc(-c2noc(CCCC(=O)NC3CCCC3)n2)cc1OC
b: CCOc1cccc(CNCCc2c(C)[nH]c3ccc(OC(F)(F)F)cc23)c1O.O=C(O)C(=O)O
Answer: b. CCOc1cccc(CNCCc2c(C)[nH]c3ccc(OC(F)(F)F)cc23)c1O.O=C(O)C(=O)O
