Solution

The correct option is B Villi
  • Pseudopodia are temporary protrusions that are filled with cytoplasm within the eukaryotic amoeboid cells and unicellular protists. Pseudopodia, also called as "false foot" are majorly used for movement and ingestion of food, nutrients and other particulate matter.
  • Villi are the finger-like projections within the small intestine that help in the absorption of nutrients from the digested food by increasing the surface are of intestine walls.
  • Lumen is the inside space of the gastrointestinal tract, through which the food is transported while digesting from mouth to anus.
Thus the correct answer is 'Villi'.
