What is the significance of Big Ben?

Big Ben refers specifically to the Great Bell of the clock at the north end of the Palace of Westminster in London and is often mistakenly used to describe the clock tower itself, which was officially renamed the Elizabeth Tower in 2012. The significance of Big Ben lies not only in its historical importance and architectural grandeur but also in its role as an iconic symbol of London and British culture. The Great Bell, which weighs over 13 tons, has been a prominent feature in London's skyline since it first chimed in 1859 and continues to resonate with both residents and visitors. Its deep, resonant chime is often associated with the passing of time, marking significant events and serving as a reminder of the nation's history.

The other options do not correctly represent the importance of Big Ben or relate to its identity and function in British culture.
