"You drink this milk."
Translation:Tu bois ce lait.
"Cet" is used in front of masculine nouns that begin with vowel sounds. Lait is masculine, but the first letter is a consonant, so you would use "ce" here.
Examples of cet + masculine noun: cet arbre, cet appartement, cet homme. (Homme is interesting because even though it begins with a consonant, the h is silent so the first sound is a vowel.)
Examples of ce + masculine noun: ce stylo, ce garçon, ce chat.
Examples of cette + feminine noun: cette femme, cette pomme, cette boîte.
I'm guessing you don't need to say 'du lait' as 'ce' indicates that you are referring to a specific carton of milk?
You are right. I wasn't paying very close attention. The correct answer vous buvez. Thanks David.
