Nonamiya [84]

The provided question is incomplete as it lacks the image required to identify the, however the correct image is attached:

Answer:

B is protein

C is the process of translation

Explanation:

The given image is a flow chart representation of the process of the protein synthesis from the DNA molecule by a two-step process that is combinedly known as the central dogma.

The first step is a transcription in which an RNA molecule (mRNA) is synthesized from the DNA molecule in organism nucleus (in eukaryotes only). The second step is to making a polypeptide chain of amino acid with help of rRNA, tRNA, and mRNA, this process is known as translation and represented in the image as C and B is the protein that formed.

Thus, the correct answer is - B is protein

C is the process of translation
