Sorry, never heard of that:(
The answer is my. It is "describing" the flowers and saying that the flowers are mine.
I, her, and everyone are pronouns that function as a noun phrase. They do/receive the action, while my is "describing" the flowers.
A choice I made , I dropped one of my closet friends , the bad consequence was I had a few friends and dropping her was a bad choice but the good part was she would always use me for my money or fame so I didn’t have to deal with her anymore
Theirs is correct because possessive forms of pronouns using the pronouns<span> yours, ours, theirs, his, and hers </span>
