<u>Answer:</u>
“All” is a determiner: Distributive determiners.
<u>Explanation:</u>
“Determiners” are words that come prior to a noun. Like, in the sentence, 'A' dog is barking. Here A is a determiner before the noun 'dog'. All articles, possessive pronouns like "my, your, his, her" and numbers like one, ten are determiners. Distributives like all, half, both are also determiners.
Articles are "a, an and the". When we want to refer to specific noun like Taj Mahal, we use ''the”. It is called definite article. In case of unspecific nouns like apple, mango, table, we use a or an. “An” is used before "vowels" (a, e, i, o, u). This is called indefinite article.
The sentence that is correctly hyphenated is "The beauty of Mount Fuji's near-perfect cone shape has enchanted people for centuries."
Near-perfect is correctly hyphenated because in this context it is a compound modifier, it modifies Mount Fuji's appearance.
