Task: Answer the MCQ question.
Query: Which drug has a 20.586% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(COC(=O)COc1cccc2ccccc12)NCC(F)(F)F
b: CCN1C=C(C(=O)OC)C(c2cccc(OC)c2OC)C(C(=O)OC)=C1
Answer: a. O=C(COC(=O)COc1cccc2ccccc12)NCC(F)(F)F
