Fill up the blank with the correct option.
I wish I _________ a King.

Correct option is D

Correct usage: "I wish I were a king."
Rule:
· In subjunctive mood, we use "were" instead of "was" after "I" to express a hypothetical or unreal situation.
Example:
· I wish she were here.
· If I were rich, I would travel the world.
Meanings of other options:
· (a) Was (Incorrect: "Was" is used in normal past tense, but this is a hypothetical situation.)
· (b) Am (Incorrect: "Am" is present tense, but the sentence expresses a wish.)
· (c) Is (Incorrect: "Is" is singular present tense, not used in subjunctive mood.)
Thus, the correct answer is option (d) "Were."
