Solution

The correct option is B 8
A bivalent is one pair of chromosomes in a tetrad. Therefore there are 16 chromosomes in prophase I. Meiosis II maintains the haploid number of chromosomes obtained after meiosis I. First meiotic division changes '2n' (16) DNA content to 'n' DNA (8) during anaphase II.
