Translation:Die Elefanten fressen Äpfel.
I'm almost sure it's "fressen" when you're talking about animals?
It's not unusual to use "essen" for anthropomorphic animals.
Where is the umlauted capital A to use for the 'correct' answer?
Hit shift before clicking on the lowercase umlauted "a", or if you stick with the keyboard you can type a lowercase e after the A to umlaut it: "Aepfel".
