Biology anabolism example

Why is D correct?

As we know that Anabolism is the set of metabolic pathways which create complex molecules from smaller units.
Option D mentions condensation which is a chemical process by which 2 molecules are joined together to make a larger, more complex, molecule, with the loss of water.
so, we are creating something complex from smaller subunits thus it is an example of Anabolism.
Hope it helps:)


Thank you for explanation.
Why photosynthesis is not anabolism? According to this webpage,Photosynthesis is an anabolic process

photolysis is the split of water into hydrogen and oxygen using light it’s part of photosynthesis but it isn’t anabolic itself :))
