Sequence represented by fruits

A person is confused about how a mathematical sequence works, to explain to her, her teacher does not use numbers and turns into sets of fruits. Which sequence is being represented by the teacher?

a. Farey Sequence
b. Sequence of prime numbers
c. Sequence of odd numbers
d. Fibonacci sequence
e. None of the previous

Can anyone help me with the interpretation of this question? I can see ways to represent all the strings (maybe not Farey’s) using fruits (which I think represent natural numbers).
