The correct option is C Connective tissue
Blood consists of fluid or liquid matrix called plasma in which white blood cells, red blood cells, and platelets are suspended.
Lymph is clear to whitish liquid in which white blood cells are suspended.
In both, blood and lymph the cells are suspended in a fluid matrix. Connective tissue contains loosely spaced cells, which are embedded in rigid, jelly-like, fluid or dense matrix. Hence, option C is correct.
