The superlative degree of an adjective is used to compare three or more things and find the one that has the highest degree or quality of that adjective. In this case, we are looking for the word that represents the highest degree of brightness.

To form the superlative degree of the adjective "bright," we need to add the suffix "-est" to the word. So, the correct answer is B. brightest.

To understand this, we can look at the three forms of comparison for adjectives:

- Positive degree: This represents the basic form of the adjective. In this case, it is "bright."
- Comparative degree: This is used to compare two things. We form the comparative degree by adding the suffix "-er" or using the word "more" before the adjective. In this case, it becomes "brighter" or "more bright."
- Superlative degree: This is used to compare three or more things. We form the superlative degree by adding the suffix "-est" or using the word "most" before the adjective. In this case, it becomes "brightest" or "most bright."

So, by applying the rules for forming the superlative degree, we can determine that B. brightest is the correct answer.
