Vedclass · Answer

(D) Chromosomes are classified based on the position of the centromere:$1$. Metacentric: The centromere is in the middle,forming two equal arms.$2$. Submetacentric: The centromere is slightly away from the middle,resulting in one shorter arm and one longer arm (unequal lengths).$3$. Acrocentric: The centromere is situated close to the end,forming one extremely short arm and one very long arm (unequal lengths).$4$. Telocentric: The centromere is at the terminal end.Since both Submetacentric and Acrocentric chromosomes possess arms of unequal lengths,the correct option is $(D)$.

Column-$I$	Column-$II$
$(a)$ Acrocentric	$(p)$ Centromere slightly away from the middle
$(b)$ Telocentric	$(q)$ Centromere in the middle
$(c)$ Submetacentric	$(r)$ Centromere near the end
$(d)$ Metacentric	$(s)$ Centromere at the terminal end
