I can't understand your question
Explanation:
Leaves are an example of homology in plants. In many plant species, leaves have been modified for functions other than photosynthesis. A cactus like Opuntia has green, flattened stem called as phylloclade, which bears a lot of spines. The cactus (Opuntia) spine and a pea tendril, although quite different in appearance, are homologous because both are modified leaves. The spine protects the succulent stem tissue of the cactus, whereas the tendril, which winds around a small object once it makes contact, helps support the climbing stem of the pea plant. Such modifications in organs used in different ways are the expected outcome of a common evolutionary origin. Hence these structures are homologous.
Therefore, the correct answer is option A.
