Fruit enlargement can be induced by spraying young ovary with

Explanation

Fruit enlargement is a process that can be induced by spraying young ovaries with certain plant hormones. The question is asking which hormones are responsible for this process. The options that are provided are gibberellins, ethylene, and abscisic acid (option A), auxin, abscisic acid, and ethylene (option B), auxin, cytokinin, and gibberellins (option C), and auxin, kinin, and gibberellin (option D). Out of the four options, the correct answer is option C, which states that fruit enlargement can be induced by spraying young ovaries with auxin, cytokinin, and gibberellins. Auxin is a plant hormone that promotes cell elongation and division, cytokinin is a hormone that promotes cell division and differentiation, and gibberellins are hormones that promote stem elongation and fruit growth. Spraying young ovaries with these hormones can cause the fruit to grow larger and ripen faster. This process is commonly used in agriculture to increase fruit yield and improve the quality of crops. It is important to note that different plant hormones have different effects on plant growth and development. For example, abscisic acid is a hormone that promotes seed dormancy and helps plants cope with environmental stress, while ethylene is a hormone that promotes fruit ripening and leaf senescence.
