Select the most appropriate option for blank(2)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. on.
The correct answer is "on" because we use "on" when referring to specific days or dates, such as "on the auspicious day of Friendship."
In this context, "on" fits best as it refers to a specific day.
The other options, "at," "in," and "over," are not used when referring to particular days, making "on" the most appropriate choice.
