Which of the following best describes the term 'bag limit'?

A bag limit refers to the maximum number of animals that a hunter is legally allowed to kill and take with them in a single day. Option A is incorrect because the term 'bag' in this context does not refer to a physical bag, but rather the act of collecting game. Option C is incorrect because the bag limit does not consider the weight of the animals, only the number. Option D is incorrect because it refers to ammunition, which is separate from the concept of a bag limit.
