Answer 1

The true statement is:

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

This is because the Calvin cycle operates in the stroma of the chloroplasts and does not require direct light to occur, although it relies on the products (ATP and NADPH) generated during the light-dependent reactions.
