Correct option is C
In this problem, the words are being substituted for different terms:
'Tree' is called 'Sky'.
'Sky' is called 'Well'.
'Well' is called 'Pond'.
'Food' is called 'Tree'.
'Water' is called 'Food'.
We are asked which of the following would provide us fruits. Normally, 'Tree' provides fruits. But according to the given substitutions:
The word 'Tree' is called 'Sky'.
So, in this code, 'Sky' is the term that actually refers to a 'Tree', which is what provides us fruits.
Thus, the correct answer is (C) Sky.
