Task: Answer the MCQ question.
Question: Which drug exhibits a -0.977% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) O=C(O)c1cn(-c2ccc(F)c(F)c2)c2c(F)c(F)c(F)c(F)c2c1=O
b.) O=C(Nc1ccc2nsnc2c1)N1CCCCCC1
Answer: a. O=C(O)c1cn(-c2ccc(F)c(F)c2)c2c(F)c(F)c(F)c(F)c2c1=O
