Correct Answer :

Option D

A-II, B-III, C-I, D-IV

A-II, B-III, C-I, D-IV

Solution :

To find the correct match between List-I and List-II, let us analyze each term one by one:

A. Centromere: The centromere is a specialized DNA sequence of a chromosome that links a pair of sister chromatids. During mitosis/meiosis (Cell division), spindle fibers attach to the centromere via the kinetochore to pull sister chromatids apart. Thus, A matches with II.

B. Cilium: Cilia are hair-like organelles that extend from the surface of nearly all mammalian cells. They play a vital role in locomotion or Cell movement, as well as in sensory functions. Thus, B matches with III.

C. Cristae: Cristae are foldings in the inner membrane of a Mitochondrion. They provide a large surface area for chemical reactions to occur, specifically cellular respiration and ATP synthesis. Thus, C matches with I.

D. Cell membrane: The cell membrane is primarily composed of a Phospholipid bilayer with embedded proteins. This structure forms a barrier that regulates the entry and exit of substances. Thus, D matches with IV.

Comparing these individual matches:
A - II
B - III
C - I
D - IV
This matches the combination given in the fourth option.
