The interaction between somatic antigens and specific antibodies is

• A. slow and fine granular sediment forms in 18-20 hrs. agglutinate do not break upon shaking
• B. rapid and fine granular sediment forms in 5-10 hrs. agglutinate do not break upon shaking
• C. rapid and large flocculi form in 2-4 hrs. agglutinate readily break upon shaking
• D. slow and large flocculi form in 3-4 days agglutinate readily break upon shaking
