select the correct answer from the choices provided in the underlined section.
light - dependent reactions / light - independent reactions take place during the day when sunlight is present.

Explanation:

In photosynthesis, light - dependent reactions need sunlight to occur as they rely on light energy to split water, produce ATP and NADPH. Light - independent reactions (Calvin cycle) can occur in the absence of direct sunlight as they use the products of light - dependent reactions and don't require light directly. So light - dependent reactions take place during the day when sunlight is present.

Answer:

Light - dependent reactions
