Answer:-
The only correct option is half the no.(number) of chromosome with respect to the parents chromosomes.
Explanation:-
Meiosis is taken from a Greek word which means lessening.
As the parent cells undergo meiosis they creates 4 haploid daughter cells with the half/halve number of chromosomes.
So as you can see it, in meiosis the number of chromosomes are halved.
History of meiosis:-
Meiosis were first discovered in 1876 by a German(particularly from Berlin) biologist named Oscar Hertwig and later some details were studied in 1883.
For further details you can see video lectures from Khan Academy, Crush course and many more.
