Explanation:
DNA is the genetic material and transfer from one generation to the generation. The DNA composed of the nitrogenous bases, pentose sugar and the phosphate group.
The base pairing of DNA follows the Chargaff's rule. According to this, the purines an pyrimidine ratio is equal to 1. The number of adenine is equal with that of thymine and number of cytosine is equal to the guanosine. In option (A) this criteria is follows.
Thus, the correct answer is option (A).
Plants produce oxygen, energy (glucose).

Answer:
C) releases oxygen into the air
Explanation:
Stomata are the minute openings present in the epidermis of leaves. Plant open stomata to take in carbon dioxide gas from the air which in turn is fixed into organic compounds during the process of photosynthesis. Oxygen gas is the by-product of photosynthesis. Plants release oxygen from stomata into the air. Therefore, dermal tissues in leaves have stomata and one of their functions is to release oxygen into the air.
