What does this indicate about the pollination process and success? A) 100% success: 100 pollen grains grew to 50 ovules, two to each, and double fertilization occurred. B) 100% success: Only 50% of the pollen grains germinated, but each produced 2 sperms to complete double fertilization in 50 seeds. C) 50% success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 50 polar nuclei.
