RRB Group D 2025 Question Paper (18-Aug-2026) (Shift 1)
The correct answer is

Plasma

Blood is a fluid connective tissue: its cells (red cells, white cells and platelets) float in a liquid matrix.

That liquid matrix is plasma, a straw-coloured fluid made mostly of water with proteins, salts, nutrients and hormones dissolved in it.

Platelets are cell fragments, haemoglobin is a pigment inside red cells, and cytoplasm is the material inside a cell.

Hence, the answer is plasma.
