Which of the following statements about sexual reproduction in flowering plants are correct? • 1. Stamen is present in the centre of a flower. 2. Stamen produces pollen grains in the ovary. 3. The swollen bottom part of carpel is the ovary. 4. The fusion of germ cells gives rise to zygote. Select the correct answer using the code given below.

Sexual reproduction in flowering plants involves specific reproductive organs. The stamen is the male reproductive part, but it is typically arranged in a whorl (androecium) around the central female part, the carpel or pistil [4]. Statement 1 is incorrect as the carpel, not the stamen, is located at the center [2]. Statement 2 is incorrect because stamens produce pollen grains in the anther, not the ovary; the ovary is the basal part of the carpel containing ovules [4]. Statement 3 is correct as the swollen bottom part of the carpel is indeed the ovary [5]. Statement 4 is correct because fertilization is defined as the fusion of male and female germ cells (gametes), which results in the formation of a diploid zygote [3]. Therefore, only statements 3 and 4 are accurate.
