Answer :
Final answer:
The phrase "all 13 clocks must strike at the same time" symbolizes the need for the 13 American colonies to unite and collaborate in their fight for independence during the American Revolution. Option D is correct.
Explanation:
The phrase "all 13 clocks must strike at the same time" is an allegorical reference used to describe the importance of unity in the American Revolution. It essentially means that all 13 colonies must work together, in sync and on the same schedule, to successfully declare independence from British rule and win the subsequent war. This was of grave significance, as lack of unity could lead to failure in the fight for freedom. It wasn't about actual clocks or timepieces, but a metaphorical way to (D) emphasize the collective work required for victory.
