Usage of "Which" in Questions:

"Which" is used to ask about a choice between a specific number of options.

Example: "Which dress do you prefer, the red one or the blue one?"

In the given sentence, the options (pink or green bag) are already mentioned, making "which" the correct choice.

Difference Between "Which" and "What":

"Which" is used when the options are already known or limited.

"What" is used when the choices are more open-ended or unspecified.

Example: "Which subject do you like more: Math or Science?" (limited options)

Example: "What is your favorite subject?" (open-ended question)
​
Additional knowledge:

Where:
"Where" is used to ask about location or place, which is irrelevant to this question.
Example: "Where is my bag?" (asking for location).

Whose:
"Whose" is used to ask about possession or ownership, not choice.
Example: "Whose bag is this?" (asking about ownership).

When:
"When" is used to ask about time, which is not relevant in this context.
Example: "When will you buy the bag?" (asking about time).
