Answer:
The correct answer is option A.
Explanation:
Carbohydrates are one of the important biomolecule present on the earth. they are made up of carbon(C), hydrogen(H) and oxygen (O) in 2:1 ratio.
The carbohydrates play significant roles in organisms as:
1. Source of energy : undergo breakdown to provide energy.
2. Storage form: glycogen in animals and starch in plants.
3. Structural role: cellulose in plant cell wall provide the structural hardness and rigidity to the cell wall. Cellulose is a polysaccharide formed by the polymerization of D-glucose via f β-1,4 linkage in linear fashion.
Thus, option A is the correct answer.

Answer:
If a strand of DNA contains the bases adenine, cytosine, cytosine and guanine the order of the bases on the opposite strand is thymine, guanine, guanine and cytosine.
Explanation:
DNA contains a double strand, each of which contains a specific sequence of bases —adenine, thymine, cytosine and guanine— whose order determines the genetic information stored in this nucleic acid.
The sequence of bases on one DNA strand is complementary on the other strand, taking into account the complementarity of bases, i.e. the purines adenine and guanine are complemented by the pyrimidines thymine and cytosine, respectively:
A = T
G ≡ C
<u>So that the sequence A - C - C - G of one chain is complemented by the sequence T - G - G - C of the other</u>.
<em> Taking into account the above information, the other options can be discarded, as they do not comply with the complementarity of bases in the DNA.</em>
