Lymph is formed by the accumulation of excess interstitial fluid, which is the fluid that surrounds cells, and the fluid that originates from capillaries through filtration. This process is driven by the pressure of blood in the capillaries, and the excess fluid is collected and transported by lymphatic vessels as lymph. Therefore, both the options B and C are correct in contributing to the formation of lymph.

Therefore, option A is incorrect.
