A
Nighttime only
B
daytime and night time
C
daytime only
D
only in the summer
Explanation: 

Detailed explanation-1: -Therefore plants perform photosynthesis only during the day in the presence of sunlight and respiration all day long. During photosynthesis, plants use light energy to convert water and carbon dioxide into oxygen and energy-rich organic compounds.

Detailed explanation-2: -Plants carry out photosynthesis only during the day and respiration only at night.

Detailed explanation-3: -Photosynthesis is not performed by plants at night. Plants can only undergo photosynthesis at night if they are exposed to the appropriate wavelengths of artificial light. With the help of the chlorophyll pigment, light energy is absorbed. By the process of photosynthesis, light energy is turned into chemical energy.

Detailed explanation-4: -Light independent reactions takes place in the stroma of chloroplast as they lack chlorophyll. Q. If a plant is releasing carbon dioxide and taking in oxygen during the day, This means that there is no photosynthesis occurring during the day time.
