The correct sequence of stages during the prophase-$I$ of meiosis is:

Which of the following statements is false?

In an organism,if the normal diploid number of chromosomes is $8$,how many chromatids are present in each daughter cell at the end of meiosis-$I$?

$S -$ Statement: In the pachytene substage,each group of chromosomes appears as a bivalent.
$R -$ Reason: During prophase in plant cells,the centriole units arranged at the two poles form spindle fibers.
