The correct option is B 20
Somatic cell is diploid (2n) in nature. It is given that the number of somatic chromosomes is 40. Seminiferous tubules contain haploid (n) spermatozoa. These spermatozoa are haploid in nature.
Hence, the number of chromosomes in the cells of seminiferous tubules will be 20.
Thus, the correct answer is '20.'
