Answer:
The pronoun that functions as an adjective in the sentence is: my.
Explanation:
There are four pronouns in the sentence: I, my, her, and everyone. The only one that functions as an adjective in this case is "my". As we know, an adjective accompanies and modifies a noun, providing more information about it. The pronoun "my" is modifying the noun "flowers", showing to whom the flowers belong.
