While - T helper cell mediated immunity provide protection against viral, and cancer cells itsits also specific type of adaptive immunity.
Q 14 answer is b - spleen, as here the most inferior structure as per body organization,
Adenoids present superior most at postr pharyngeal wall roof.
Then thymus in tracheal region at bifurcation of trachea, then axillary lymph node, and crystina chyli at thorasic cavity and most inferior is the spleen in abdominal cavity at left quadrant below stomach, lateral to pancreas.
