I is true — blood is connective tissue (cells in a fluid matrix).
II is true — plasma is ~90% water.
III is false — tonsils trap some pathogens at the throat, but most inhaled particles are filtered by nasal hairs, mucus, cilia and other parts of the respiratory mucosa, not mainly by the tonsils.
IV is true — lymph drains back into the blood via the thoracic and right lymphatic ducts near the shoulder/clavicle region.
