The true statement is:

The Calvin cycle is the light-independent (does not need light) step of photosynthesis and happens in the stroma.

The Calvin cycle occurs in the stroma of chloroplasts and does not directly require light; instead, it uses the products of the light-dependent reactions (ATP and NADPH) to fix carbon dioxide into organic molecules.
