    Stroma

  • B

    Cytosol

  • C

    Thylakoid Membrane

  • D

    No specific location

Explanation

The Calvin Cycle, also known as the dark reactions or light-independent reactions of photosynthesis, occurs in the stroma of the chloroplasts. The chloroplast is an organelle found in plant cells and some other eukaryotic cells, and it is the site of photosynthesis.

The Calvin Cycle, also known as the dark reactions or light-independent reactions of photosynthesis, occurs in the stroma of the chloroplasts. The chloroplast is an organelle found in plant cells and some other eukaryotic cells, and it is the site of photosynthesis.

Calvin cycle doesn't occur in cytosol although cytosol is a site of metabolic processes such a glycolysis.

Light reaction of photosynthesis occurs thylakoid membrane howevere, calvin cycle or dark reaction occurs in stroma.

This is incorrect. The Calvin Cycle, also known as the dark reactions or light-independent reactions of photosynthesis, occurs in the stroma of the chloroplasts. The chloroplast is an organelle found in plant cells and some other eukaryotic cells, and it is the site of photosynthesis.
