1) Thylakoid membrane 2) Envelope membrane

B) Calvin cycle occurs within the stroma, while light reactions occur within the thylakoid membrane.

Explanation:

Generally, the chloroplast is made up of the; <u>Thylakoid membrane and Envelop membrane</u>. The thylakoid membrane is basically the region for light absorption, thus making it the site for light reactions within the chloroplast.  

Calvin cycle, which occurs in the stroma, involves light independent reactions. It occurs shortly after the light-dependent reactions, and further breaks down ATP and NADPH, products of the light reactions.

The stroma is located outside the thylakoid membrane.

For the remaining listed organelles:

1) The Cytosol- It’s the liquid space within the cell. The chloroplast can be found floating within the cytosol of any involved plant cell.

2) Thylakoid space- The space within the thylakoid.
