Answer
(A) Sugar, phosphate and bases: These are components of DNA but do not include proteins, which are critical in chromosome structure.
(B) Lipids, DNA and protein: While DNA and proteins are present in chromosomes, lipids are not a component of chromosome structure.
(C) DNA and protein: This option includes the two primary components of chromosomes.
(D) Genes and DNA: While genes are segments of DNA, this option excludes proteins.
