The correct answer is that parts of London were destroyed by a fire, specifically referencing the Great Fire of London, which occurred in 1666 during the reign of Charles II. This catastrophic event resulted in a significant portion of the city being engulfed in flames, leading to the destruction of thousands of homes, numerous churches, and important buildings, including St. Paul's Cathedral. The fire lasted for several days and had a profound impact on the landscape of London, prompting rebuilding efforts that led to new architectural developments and urban planning initiatives.

While other events mentioned in the options, such as the Great Plague, did affect London during Charles II's time, they did not cause destruction in the physical sense in the same way that the fire did. Bombing during WWII and natural disasters also led to destruction in London, but those events occurred long after the reign of Charles II. Hence, the devastation caused by the fire is the primary reason why this answer is the most accurate in the context provided.
