Fusion of one male gamete with the egg is called syngamy whereas another make gametes with the polar nuclei forms triploid endosperm. Thus two make gametes are fertilizing with polar nuclei and the egg cell .so, It is called double fertilization.

**Double Fertilization:**
Double fertilization is a unique reproductive mechanism found in flowering plants (angiosperms). It involves the fusion of two male gametes with two female gametes, resulting in the formation of both the zygote and endosperm. This process is essential for the successful development of seeds in plants.
**Explanation of the Correct Answer (Option C):**
Option C states that double fertilization involves the fusion of one of the male gametes with the secondary nucleus and the other male gamete with the egg cell. Let's break it down step by step:
1. **Male Gamete Fusion with the Secondary Nucleus:** During the process of double fertilization, one of the male gametes (sperm cells) fuses with the secondary nucleus located within the embryo sac. The secondary nucleus is also known as the central cell or the polar nucleus.
2. **Formation of the Primary Endosperm Nucleus:** The fusion of the male gamete with the secondary nucleus results in the formation of the primary endosperm nucleus (PEN). This nucleus is triploid (3n) because it contains two sets of chromosomes from the male gamete and one set of chromosomes from the secondary nucleus.
3. **Male Gamete Fusion with the Egg Cell:** Simultaneously, the other male gamete fuses with the egg cell (ovum) present in the embryo sac. This fusion results in the formation of a diploid (2n) zygote, which is the fertilized egg.
4. **Development of the Embryo and Endosperm:** The zygote develops into the embryo, which eventually gives rise to the new plant. The primary endosperm nucleus, on the other hand, undergoes multiple rounds of mitosis to form the endosperm. The endosperm serves as a nutritive tissue for the developing embryo.
In summary, option C correctly describes double fertilization in angiosperms, where one male gamete fuses with the secondary nucleus to form the primary endosperm nucleus, and the other male gamete fuses with the egg cell to form the zygote. This process ensures the development of both the embryo and endosperm, which are crucial for seed formation and plant reproduction.
