The answer is b because water has a PH of 1 and lemon juice is very acidic
C is true.
A is definitely false, since photosynthesis does not occur in petals, but in the leaves (or the portions with green pigmentation)

If you are going from a high gradient to a low gradient it’s passive transport. Think of a hill if you put a rock at the top of that hill it will go down no energy involved. Active transport is going up the hill you must use energy to push that rock up the hill because it’s from a low gradient to the top. Hope this helps
