Topic: Degree of Comparison,

Best Answer Explained in Below-:

The term "hugest" is not considered standard English, making it the correct choice for "not correct" among the provided options. While "tallest," "largest," and "biggest" are all widely accepted comparative and superlative forms, "hugest" tends to be seen as nonstandard or colloquial and is rarely used in formal contexts.

In English, "big" is commonly used in comparative forms such as "bigger" and "biggest." However, "hugest" is an irregularity that some speakers may use informally, but it lacks acceptance in formal grammar. The adjective "huge," which means very large in size, does not follow the regular morphological patterns to form its superlative. Instead, it is more appropriate to use "biggest" to convey the same meaning while adhering to standard English.

In summary, the grammatically correct superlative forms would be "tallest" (for height), "largest" (for size or volume), and "biggest" (for overall magnitude), while "hugest" remains an informal and questionable variant. Therefore, option A is indeed the most accurate choice for "not correct."
