Answer: Option B

• The idiom "rake up" means to bring up something that happened in the past and is now better forgotten.
• The word "quarrel" refers to an argument or a disagreement between two or more people.
• So, the idiom "rake up an old quarrel" means to revive or bring back a past disagreement or argument that has already been resolved or forgotten.

Let's understand the meaning of the options to see why option B is the correct answer.
Option A. Forget - This option is incorrect because "raking up" means the opposite of forgetting something. It means to revive or bring up something from the past.
Option B. Revive - This option is correct because "rake up" means to bring back or revive a past disagreement or argument.
Option C. Start - This option is incorrect because "rake up" refers to something that has already happened in the past, so it cannot mean to start something new.
Option D. End - This option is incorrect because "rake up" refers to something from the past, and it cannot mean to end something.
Option E. None of these - This option is incorrect because option B is the correct answer.
In conclusion, the correct meaning of the given idiom is "revive" or to bring back a past disagreement or argument that has already been resolved or forgotten.
