Explanation:

- The given sentence implies the monkey's head was removed or destroyed using a rifle.

- Option 1: "blows" - This is incorrect. "Blows" is a noun meaning hits or strikes and doesn't fit in the context.

- Option 2: "blown" - This is correct. "Blown away" is a phrase commonly used to describe something being destroyed or removed with force, fitting the context of using a rifle.

- Option 3: "blew" - This is incorrect. "Blew" is the past tense of "blow" but isn't used in this context to describe something being destroyed by force.

- Option 4: "sharp" - This is incorrect. "Sharp" describes something with an edge or point, unsuitable here.

- Option 5: "created" - This is incorrect. "Created" means to bring something into existence, unrelated to the context.
