Answer :

Answer:

the answer is: A) growth of actin filaments to form bulges in the plasma membrane.

Explanation:

Amoebas are unicellular organism that can move on a surface using pseudopodia (false feet). This kind of movement is called amoeboid movement. The amoeboid movement is explained by the Sol-gel theory.  The protoplasm of the amoeba is made of an outer gelatinous layer, and an inner portion made up of plasma sol. The sol-gel theory explains the contraction and relaxation events in the protoplasm of the amoeba that lead to the pseudopodia.
