(B) The root tip cells of a plant are diploid $(2n)$.Given that $2n = 42$,the haploid number $(n)$ is $42 / 2 = 21$.The endosperm in angiosperms is formed by the fusion of one male gamete $(n)$ with two polar nuclei $(n + n)$,resulting in a triploid $(3n)$ structure.Therefore,the number of chromosomes in the endosperm cells = $3n = 3 	imes 21 = 63$.

If a plant has $42$ chromosomes in its root tip cells,then the number of chromosomes in its endosperm cells is:
