Answer:
In the photo, we can see two things, a tongue, and two legs.
Tongue in Spanish is called "lengua", and like most of the words that end in a, is a feminine word, so the correct option for lengua is "Larga".
In the second image, we can see two legs, that are called "Piernas" in Spanish, and it is also a feminine word, but in this case, is plural (because there are two of them) so the correct option here is "Largas"
