Match List-I with List- II.

	List-I		List-II
A.	Centromere	I.	Mitochondrion
B.	Cilium	II.	Cell division
C.	Cristae	III.	Cell movement
D.	Cell membrane	IV.	Phospholipid Bilayer

Choose the correct answer from the options given below :

To match each term in List‑I with the appropriate description in List‑II, consider the biological function or structure each term represents.

Centromere is the region of a chromosome where the sister chromatids are joined and where spindle fibers attach during mitosis. Therefore it is directly involved in cell division, which corresponds to option II.

Cilium is a hair‑like projection on the surface of many cells that beats to produce movement, enabling the cell to move or to move fluid across its surface. Hence it matches cell movement, option III.

Cristae are the internal folded membranes of a mitochondrion**, increasing surface area for oxidative phosphorylation. Thus they correspond to option I.
