Final answer:
The sentence indicating that the golden hour's duration isn't exactly one hour suggests the term shouldn't be taken literally.
Step-by-step explanation:
The sentence from the passage that supports the idea that the name golden hour is not to be taken too literally is: B. Photographers cherish this time of day, but it's not actually an hour long.
This sentence directly addresses the misconception that the golden hour lasts for a precise 60 minutes, rather suggesting that its duration is variable and not to be understood strictly by its name.
