In Plants photosynthesis can only take place in the presence of sunlight during the day, respiration happens all day long, hence option c is correct.

What is respiration in plants?

Plants' respiration is visible at night and day, plants consume oxygen during respiration while also releasing carbon dioxide. Both photosynthesis and respiration take place during the day.

However, only respiration takes place at night, which uses oxygen. A sequence of chemical processes known as cellular respiration converts glucose into ATP, which may then be utilized as energy for a variety of bodily functions.

Glycolysis, citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.

Therefore photosynthesis takes place during the day but plants respire all the time, hence option c is correct.
