Match the following and select the correct answer.

(A) Centriole	(i) Infolding in mitochondria
(B) Chlorophyll	(ii) Thylakoids
(C) Cristae	(iii) Nucleic acids
(D) Ribozymes	(iv) Basal body cilia or flagella

The correct option is A A = (iv), B = (ii), C = (i), D = (iii)
Basal bodies are modified centrioles that give rise to cilia and flagella. In the cell, apex is the basal body that is the anchoring site for a flagellum. Chlorophyll is found in high concentrations in chloroplasts of plant cells. Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Chlorophyll molecules are specifically arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts. The inner membrane of the mitochondrion folds inwards, forming the cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion. Ribozymes (ribonucleic acid enzymes), also termed RNA molecules are capable of catalyzing specific biochemical reactions, similar to the action of protein enzymes. RNA can be both genetic material (like DNA) and a biological catalyst like protein enzymes.

Hence the correct option is A.
