{'seedless tomato fruits': [0, 1, 0, 0], 'tomato fields': [0, 1, 0, 0], 'fertilizers': [0, 0, 0, 1], 'plants': [11, 0, 4, 4], 'radioactive elements': [0, 1, 0, 1], 'trace elements': [0, 1, 0, 0], 'mineral solution': [0, 1, 0, 0]}

Option 1, applying trace elements in tomato fields, is incorrect because while trace elements are essential for overall plant health and productivity, they do not directly influence the generation of seedless fruits.

Option 2, spraying mineral solutions on plants, is also incorrect. Minerals do support the growth and development of plants, but their application doesn`t directly result in the production of seedless tomatoes.

Option 4, applying fertilizers containing radioactive elements, is not a valid method for producing seedless tomatoes. While radioactive elements can cause genetic changes in plants, they pose serious health and environmental risks, and there`s no evidence to suggest they could produce seedless fruits.

The correct answer is indeed option 3, spraying hormones on flowers. This method directly affects the development of the ovary (which becomes the fruit) and can prevent the formation of seeds. Hormones such as gibberellins are commonly used to produce seedless fruits. By spraying these hormones, it`s possible to develop seedless tomatoes.
