• A. A-(ii),B-(iii),C-(i),D-(iv)
• B. A-(i),B-(ii),C-(iii),D-(iv)
• C. A-(iv),B-(ii),C-(i),D-(iii)
• D. A-(ii),B-(i),C-(iii),D-(iv)

Answer 1

Answer: (A)

A-(ii),B-(iii),C-(i),D-(iv)

Prophase is the short phase where there is no pairing of the chromosome and this is the first phase where the disintegration of the nuclear membrane takes place and the chromatin appears as a ball of wool.

During the S phase which is the synthetic phase of the interphase and here the DNA replication takes place and its amount become double.

In the anaphase, the division of centromere takes place and the chromatids separate and move towards opposite poles.

Telophase is the stage where the nuclear membrane starts integrating and all the cellular organelles can be seen again and here the nucleus starts forming.

Thus, the correct answer is 'A-(ii),B-(iii),C-(i),D-(iv).'
