Final answer:
The appropriate word to fill in the blank is 'Comparte'.
Step-by-step explanation:
The appropriate word to fill in the blank would be D. Comparte.
This is because the sentence is in the second person singular form (Tú tienes), so the verb 'compartir' must also be conjugated in the second person singular form, which is 'comparte'.
The sentence would then mean 'You have enough strawberries for everyone. Share the strawberries, please.'
