• A. Germination
• B. Photosynthesis
• C. Respiration
• D. Pollination

Answer: (D)

Pollination is the transfer of pollen from the anther to the stigma, often aided by wind or pollinators. This step is what enables fertilization and seed production in flowering plants, because pollen reaching the stigma allows pollen tubes to grow toward the ovules. The other processes are different: germination is when a seed begins to grow after dispersal; photosynthesis is how plants convert light energy into chemical energy; respiration is the cellular process that releases energy from glucose. Since the description focuses on moving pollen between the male and female floral parts, it correctly identifies the process as pollination.
