C'est + quoi
In spoken French, "C'est quoi" is an informal way to ask "What is..." and is used before a noun or phrase.
Possessive adjective "ta"
"Ta" agrees with the feminine singular noun that follows (matière). Use "ton" for masculine nouns.
Adjective agreement
The adjective "préférée" must agree in gender and number with the noun "matière" (feminine singular), hence the extra "e".

The interrogative "Quel" must agree with the noun; use "Quelle" for feminine nouns like "matière".
ta matière préféré
The adjective must match the gender of "matière" (feminine), so add the final "e".
C'est quel ta matière préférée ?

Cultural Tip
