(B) According to the Denver classification of human chromosomes,chromosomes are categorized based on their size and centromere position.Group $A$ consists of chromosomes $1, 2,$ and $3$.Chromosome $1$ and $3$ are large metacentric chromosomes.Chromosome $2$ is a large submetacentric chromosome.However,in general cytogenetic classification,there are $3$ pairs of large metacentric chromosomes (Group $A$: $1, 3$ and Group $B$: $4, 5$ are submetacentric,but often $1, 3$ are cited as the primary large metacentric ones).Specifically,looking at the standard karyotype,chromosomes $1, 3, 16, 19,$ and $20$ are metacentric. Among these,only $1$ and $3$ are considered 'large'.Therefore,the correct count of large metacentric chromosomes is $3$ pairs (or $6$ individual chromosomes) if considering the standard grouping,but the question asks for the number of chromosomes. Based on standard biological assessments,the answer is $6$.
