Detailed Solution

At metaphase, chromosomes are aligned at the equator and each chromosome has two chromatids.
(1) It is not showing any splitting of centromere and separation of chromatids though spindle fi bres are
attached to kinetochores.
(3) It is not anaphase as there is no splitting of centromere and separation of chromatids.
(4) It is not late prophase as the chromosomes are present perfectly at the equator and spindle apparatus is
completely organised. It is metaphase.
