Letâs study the given diagrams showing the cross-section of two flowers carefully: Flower X shows Sepals, Petals and Pistil. There is no Stamen. Flower Y shows Sepals, Petals, Stamens and Pistil. Pistil is the âfemaleâ part of a flower, as it produces seeds. Stamen is the âmaleâ part of a flower, as it produces pollen. Now, letâs check the given statements, and find out which ones are correct: (i) Both flowers will produce female gametes. ----- Correct. Since both flowers have Pistil, they both can produce female gametes, or seeds. (ii) Flower X is a female flower and flower Y is a bisexual flower. ----- Correct. Flower X only has Pistil, so it is a female flower. Flower Y has both Stamen and Pistil, so it is a bisexual flower. (iii) Self pollination can take place in both flowers. ----- Incorrect. Since only flower Y has both Stamen and Pistil, self pollination can take place on flower Y only. Only Statements (i) and (ii) are correct, so the right answer is Option C

Hi! I had the same doubt in mind, but I found the same picture on google which was much more clearer. Even in this picture you can see anthers on the side of the pistil. Thus, the answer should actually be (i) and (iii). But that is not there in the options.
Take Care and Hope You Understand :)

The correct answer is C.

The answer should be (i) only as we can clearly see anthers on the side of flower X, but it can't self-pollinate because the anther is a lower altitude than the stigma, hence the stigma cannot receive the pollen grains. So, I still think the answer should be (i).
