The correct answer is option (B):
make a determined effort
The phrase "fight tooth and nail" is an idiom. Idioms are phrases where the meaning of the words together is different from the literal meaning of the individual words. "Fight tooth and nail" describes a struggle where someone fights with all their strength and determination, using every available means.
Let's look at the options:
* "bite and scratch your enemy": This describes a very direct, physical form of fighting. While it is a part of fighting tooth and nail, it doesn't encompass the complete meaning. Fighting tooth and nail means more than just physically fighting.
* "make a determined effort": This is the closest and most accurate equivalent. "Fight tooth and nail" implies a strong effort, a refusal to give up, and a dedication to achieving a goal, regardless of the difficulty.
* "inflict equal damage": This phrase focuses on the result of the fight, not the effort. While "fighting tooth and nail" might result in equal damage, the phrase itself emphasizes the intensity of the struggle.
* "pull out enemy's teeth and nails": This is a literal interpretation of the phrase, which makes no sense in the context of the idiom. It doesn't convey the intended meaning of a fierce and unrelenting struggle.
Therefore, "make a determined effort" accurately reflects the overall meaning of fighting with all your available strength and determination, as implied by the idiom "fight tooth and nail".
