Couple of questions. Where is the "can" in the correct answer? The example Hungarian seems to me like "we do not see the apples".
Also, why is " mi" important to this sentence? Is the subject not clear from the verb case?
Can anybody explain why this turns into Látjuk?
You need to use a definite verb here, because of "az almákat" (definite accusative). The definite verb form in this case is látjuk (the indefinite would be látunk).
Én látom, te látod, ő látja, mi látjuk, ti látjátok, ők látják.
