(C) In angiosperms,the formation of a seed involves the fusion of a male gamete with an egg cell to form a zygote (which develops into an embryo) and the fusion of a male gamete with two polar nuclei to form the primary endosperm nucleus (which develops into endosperm).For the production of $1$ seed,$1$ meiotic division is required for the formation of the female gametophyte (megasporogenesis) and $1/4$ meiotic division is required for the formation of male gametophytes (microsporogenesis).Total meiotic divisions for $1$ seed = $1 + 1/4 = 5/4 = 1.25$.For $100$ seeds,the total number of meiotic divisions required = $100 	imes 1.25 = 125$.
