B Correct answer
Explanation

Telomeres are DNA sequences at chromosome ends (1-B). Kinetochores are protein structures where spindle fibers attach (2-D). Centromeres are DNA sites where kinetochores are found (3-A). Nucleolar organizers are DNA sequences that serve as templates for ribosomal RNA synthesis and amplification (4-C). Option B correctly matches these.
