a. water + carbon dioxide + sunlight → oxygen + glucose
b. carbon + oxygen → carbon dioxide
c. hydrogen + oxygen → water
d. nitrogen + hydrogen → ammonia

Explanation:

Photosynthesis is the process by which plants use sunlight to convert water and carbon dioxide into oxygen and glucose. Option A correctly represents this reaction with the required reactants (water, carbon dioxide, sunlight) and products (oxygen, glucose). Other options describe different chemical reactions unrelated to photosynthesis.
