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

Answer 1

Answer: (B)

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

During anaphase depending upon the position of the centromere, chromosomes are classified into four types metacentric, submetacentric, acrocentric and telocentric. Metacentric chromosomes have the centromere in the center, such that both sections are of roughly equal in length and appear V-shaped at anaphase. Submetacentric chromosomes have the centromere slightly offset from the center leading to a slight asymmetry in the length of the two sections and appear L-shaped at anaphase. The acrocentric chromosome has the centromere located quite near one end of the chromosome and appears J-shaped at anaphase. Telocentric chromosome have centromere is located at the terminal end of the chromosome and appear I-shaped at anaphase.

So. the correct answer is 'option B'
