Match List-$I$ with List-$II$:

List-$I$ List-$II$

$(a)$ Metacentric chromosome $(I)$ Centromere situated close to the end forming one extremely short and one very long arm

$(b)$ Acrocentric chromosome $(II)$ Centromere at the terminal end

$(c)$ Sub-metacentric $(III)$ Centromere in the middle forming two equal arms of chromosomes

$(d)$ Telocentric chromosome $(IV)$ Centromere slightly away from the middle forming one shorter arm and one longer arm

Choose the correct answer from the options given below:

List-$I$	List-$II$
$(a)$ Metacentric chromosome	$(I)$ Centromere situated close to the end forming one extremely short and one very long arm
$(b)$ Acrocentric chromosome	$(II)$ Centromere at the terminal end
$(c)$ Sub-metacentric	$(III)$ Centromere in the middle forming two equal arms of chromosomes
$(d)$ Telocentric chromosome	$(IV)$ Centromere slightly away from the middle forming one shorter arm and one longer arm
