Given what we know, we can confirm that the correct option is D, which states that "<em><u>They are used by living things as the </u></em><em><u>main source </u></em><em><u>of </u></em><em><u>energy</u></em>."
<h3>What are carbohydrates?</h3>
- They are the primary source of energy for most cells.
- They are what we refer to as sugars.
- The main example of this is glucose.
- They are formed by monomers called monosaccharides.
Therefore, we can confirm that since carbohydrates are what we refer to as sugars, which include molecules like glucose and this is the main source of energy for most cells, option D is the correct choice.

The answer is <span>B) three chromosomes in any one set.
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes (so choice C. does not indicate a genetic problem). There are in total 46 chromosomes (23 pairs in 2 copies), that differs in lengths (so choice D. does not indicate a genetic problem). Speaking of a pair of sex chromosomes, there could be two X chromosomes in females or one X and one Y chromosome in males (so choice A. </span><span>does not indicate a genetic problem).
But, having three chromosomes in </span>any one set suggests a presence of trisomy, which is <span> a condition in which an extra copy
of some chromosome is present. This results in a genetic disorder.</span>
