Chromosomes are composed of
-
DNA and vitamins
-
DNA and proteins
-

Correct answer
Explanation
Chromosomes are made of DNA and proteins (specifically histones). The DNA wraps around histone proteins to form the chromatin structure, which then condenses into chromosomes during cell division. Vitamins and lipids are not structural components of chromosomes. Option D is incorrect because it excludes DNA, which is the genetic material.
