Q. Which one is abundant in lymph

Explanation by: Kirti

Lymph is a fluid that is similar to plasma but has a different composition. It contains:
Proteins: Lymph has some proteins, though in lower amounts than blood plasma.
Water: Lymph is mostly water, but it is not the defining component.
Lipids: Lymph absorbs fats from the intestines, but lipids are not the most abundant component.
Oxygen: Lymph is not primarily involved in oxygen transport.
Thus, proteins are the most abundant among the given options.
