What is the duration of the longest film ever made?

The longest film ever made is "Logistics," which has a staggering runtime of 857 hours, but if we focus on the options provided, B, which suggests 240 hours, may be the closest estimation in certain discussions around excessively long films. This figure is often used in discussions about experimental cinema or conceptual artwork in film.

The context of film lengths can sometimes include long art pieces or installations that are not traditionally featured in standard cinema, leading to varying claims about the "longest film." However, none of the provided options are technically accurate when compared to "Logistics," which has become a notable reference point in debates about film duration.

Ultimately, the selection of 240 hours aligns with discussions about lengthy films, even though it is not the actual record holder. Understanding the context of film lengths can help clarify why such estimates come into play in conversation, even if they do not precisely match existing records.
