1.This figure is wrong;please strike it-----(fill in with suitable preposition)
This figure? What is the figure?
Well, you could strike it up, like "Strike Up the Band", or strike it down, like a law that's unconstitutional. What do you think? Maybe use White-out?
1. This figure is wrong; please strike it **out**.
To correct the sentence "This figure is wrong; please strike it," you can use the preposition "through" to indicate the action of striking and removing the figure. The revised sentence would be:
"This figure is wrong; please strike it through."
