A true fruit is formed from

Explanation

This question is asking about the definition of a true fruit. The question provides five options, from which you are to select the correct one. The options are: A) fertilized ovary and other floral parts, B) a fertilized ovary, C) a fertilized ovary and calyx, D) a fertilized and fleshy receptacle, and E) an unfertilized ovary and other floral parts. A true fruit is a fruit that develops from a fertilized ovary. This means that after a flower has been pollinated, the ovary of the flower will develop into a fruit. The fertilized ovary will contain the seeds of the plant. The other parts of the flower, such as the petals, sepals, and stamens, may or may not be present in the mature fruit. Option B, a fertilized ovary, is the correct answer because a true fruit is formed from a fertilized ovary alone, without the other floral parts. Option A, fertilized ovary and other floral parts, is incorrect because a true fruit does not require other floral parts to form. Option C, a fertilized ovary and calyx, is also incorrect because the calyx is a part of the flower, not the fruit. Option D, a fertilized and fleshy receptacle, is incorrect because a fruit formed from a fleshy receptacle, such as an apple, is not a true fruit. Option E, an unfertilized ovary and other floral parts, is incorrect because an unfertilized ovary cannot form a true fruit. In summary, the correct answer to this question is Option B, a true fruit is formed from a fertilized ovary
