Fill in the blanks with the correct French definite or indefinite articles.

1. C'est C. la gomme de Marie.
"Gomme" is a feminine singular noun, so the definite article "la" is used.

2. J'ai A. des stylos dans mon sac.
"Stylos" is a plural noun, and "des" is the indefinite article for plural nouns, meaning "some".

3. B. L' ordinateur est sur la table.
"Ordinateur" is a masculine singular noun that starts with a vowel. The definite article "le" contracts to "l'" before a vowel.

4. Regarde ____ oiseaux dans le ciel !
The options for this question are incomplete in the provided image. "Oiseaux" is a plural noun. Neither "le" (masculine singular) nor "la" (feminine singular) would be correct. The correct definite article for a plural noun is "les".
