The correct answer is option 3, vegetative bud. The edible part of a cabbage plant is not a fruit, as mentioned in option 1. Cabbage does not produce a fruit like other plants. The edible part of the cabbage is also not a condensed flower, as stated in option 2. While cabbage does have flowers, they are not the part that is typically consumed. Option 4, inflorescence, is also incorrect because it refers to a structure that holds multiple flowers, which is not the part that is eaten. Instead, the part of the cabbage plant that is consumed is the vegetative bud. This bud is formed at the center of the cabbage plant and is harvested when it is still tightly packed and before it blooms into flowers.
