both red both white one red and one white one white and one pink
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: In snapdragon plants, red flowers are dominant to white flowers. When red-flowered plants are crossed with white-flowered plants, pink flowers are produced. If a researcher wants to produce plants with only white flowers, what color should the parent plants be?
Possibilities:
- both red
- both white
- one red and one white
- one white and one pink

both white
