Which interrogative pronoun should replace the blank space in the following sentence?: ___ locker is mine?

Mar 11, 2018

Which.

Explanation:

You're asking which locker that has been assigned to you, assuming that there is more than one locker, then you would make the interrogative pronoun, as opposed to asking if one particular locker is yours.

Example: $W h i c h$ locker is mine?

Example 2: Is $t h i s$ locker mine?
