Answer:

Correct Answer: A

Solution:

[a] Pair of anaphase I with their feature is correctly matched.

Metaphase I: Spindle apparatus appear and the chromosomes are arranged on equatorial plate, with the centromeres towards the pole.

Spindle fibres become attached to the centromeres of the two homologous chromosomes.

Interphase: It is the time during which cell is preparing for division by undergoing both cell growth and DNA replication.

Prophase I: It is the lengthy phase when compared with mitotic phase.

It is subdivided into 5 sub-phases: leptotene, zygotene, pachytene, diplotene and diakinesis.
