To solve this problem, we need to understand the process of double fertilization in flowering plants.$\newline$In angiosperms, the male gametes are discharged into one of the synergids. Let's analyze the fate of these male gametes:$\newline \bullet$One of the male gametes fuses with the egg cell to form a diploid zygote. This process is known as syngamy.$\newline \bullet$The other male gamete fuses with the two polar nuclei present in the central cell of the embryo sac. This fusion results in the formation of a triploid primary endosperm nucleus. This process is known as triple fusion.$\newline$Together, syngamy and triple fusion constitute the process of double fertilization, which is a characteristic feature of angiosperms.$\newline$Therefore, the correct fate of the male gametes is:$\newline$One fuses with the egg and the other fuses with the central cell nuclei.$\newline$This corresponds to Option 4.
