Read the passage carefully and answer the questions
Optically active polyhydroxy aldehydes or ketones or molecules which provide such units on hydrolysis are called carbohydrates. They can be broadly classified as monosaccharides, disaccharides and polysaccharides depending on their behavior towards hydrolysis. They are also classified as reducing or non-reducing sugars. Another class of biomolecules is proteins which are polymers of twenty different amino acids linked by peptide bonds. Amino acids can be classified as acidic, basic or neutral depending on the relative number of amino and carboxyl groups in their molecule. The essential amino acids cannot be synthesized by our body and hence must be provided through diet. Nucleic acids are the polymers of nucleotides which in turn consist of a base, pentose sugar and phosphate. There are two types of nucleic acids namely, DNA and RNA which differ in the composition of sugar and a base
Four bases present in RNA molecule are

Which of the following is the correct statement?
A. The solubility of gases in liquids increases with a decrease of pressure.
B. If the dissolution process is endothermic, the solubility should increase with a rise in temperature.
C. If the dissolution process is endothermic, the solubility should decrease with a rise in temperature.
D. If the dissolution process is exothermic, solubility will not change with a increase in temperature.
E. If the dissolution process is exothermic, solubility should increase with an increase in temperature.
