Translation is the second process that occurs in protein synthesis. It is the process whereby mRNA template is used to synthesize an amino acid sequence, which eventually becomes a protein.
The process of translation occurs in the cytoplasm (specifically in the ribosome). As depicted in this image, the mRNA produced during transcription is transported out of the nucleus into the cytoplasm. A RNA molecule called tRNA reads the mRNA sequence (codon by codon) and carries corresponding amino acid into the growing amino acid sequence.
Hence, according to this question, the process occuring at B according to this image is TRANSLATION.
Maybe not because after light increases stomas will decrease and after that plant leaf will take less co2 and less co2 mean less synthesis in the plant.
