C Correct answer
Explanation

Many algae (especially certain groups like green algae Chlamydomonas) have chloroplasts that lack grana stacks - their thylakoid membranes are unstacked. Higher plants (shrubs, herbs, trees) all have well-developed grana stacks in their chloroplasts for efficient light capture.
