To solve this problem, we need to identify the type of chromosome based on the position of the centromere.$\newline$Let's analyze the given options:$\newline \bullet$Metacentric:$\newline$ - In metacentric chromosomes, the centromere is located in the middle, resulting in two arms of equal length.$\newline$ - This matches the description given in the question.$\newline \bullet$Telocentric:$\newline$ - In telocentric chromosomes, the centromere is located at the very end of the chromosome, resulting in only one arm.$\newline$ - This does not match the description given in the question.$\newline \bullet$Sub-metacentric:$\newline$ - In sub-metacentric chromosomes, the centromere is slightly off-center, resulting in one arm being longer than the other.$\newline$ - This does not match the description given in the question.$\newline \bullet$Acrocentric:$\newline$ - In acrocentric chromosomes, the centromere is located closer to one end, resulting in one very short arm and one long arm.$\newline$ - This does not match the description given in the question.$\newline$Therefore, the correct answer is Option 1: Metacentric.
