Final answer:
Mr. Green uses his gun to defend himself against Miss Scarlet’s lunge, indicating that the correct answer to the question is d) Mr. Green defends with the gun. Option d.
Step-by-step explanation:
Based on the scene described, the correct option is d) Mr. Green defends with the gun. The phrase “He staves her off with his gun” indicates that Mr. Green is using his gun to keep Miss Scarlet at bay, therefore, he is defending himself using the weapon.
There is no indication that Miss Scarlet denies or dismisses the gun; rather, she lunges at Mr. Green, which suggests she is on the offensive. However, it is ultimately Mr. Green's action with the gun that defines the correct answer as defensive rather than offensive on Miss Scarlet's part.
So Option d .
