Let's use process of elimination to answer this question!
D is wrong, and we know this because of the names of DNA and RNA. The D in DNA stands for deoxyribose, and the R in RNA stands for ribose. These are the types of sugars in each nucleic acid. Therefore, they don't both contain a ribose sugar.
C is wrong, and this is because RNA does not contain thymine, but uracil instead.
B is wrong, and we know this because we know that RNA is composed of only one strand, and therefore it is not composed of multiple stands (plural).
Therefore, A must be right. We can confirm this, because we know that polymers are large molecules consisting of repeated subunits. DNA and RNA are both polymers consisting of nucleotides.<span />
Answer:

it would be problematic if the esophagus was lined with simple squamous epithelium because it is exposed to dryness or to abrasion as a result of the presence of keratin.
<h3>What is Simple squamous epithelium?</h3>
This is the type of epithelium which are present in blood vessel and the cells of the lungs such as alveoli etc.
This type of cell is absent in the esophagus because it has the ability to get dried up or abrased as result of food substances which are taken in which may cause different complications in the body.
This is therefore the reason why the stratified squamous epithelium is responsible for the lining of the esophagus.
