Correct answer: A

Rationale: Rationale: Phagocytes are a type of white blood cell that plays a crucial role in the immune system by engulfing and digesting foreign invaders such as bacteria, viruses, and other harmful substances. They are part of the body's innate immune response and are essential for protecting the body against infections. Lymphocytes, on the other hand, are another type of white blood cell involved in the adaptive immune response, producing antibodies and coordinating immune responses. Platelets are cell fragments involved in blood clotting, while red blood cells are responsible for carrying oxygen to tissues.

Microfilaments are involved in generating forces for cell motility and maintaining cell shape, making option B, 'Facilitate cell movement and contraction,' the correct choice. The other options are not accurate for microfilaments: A) Structural support and shape are primarily provided by intermediate filaments, C) Mitotic spindle formation is attributed to microtubules, and D) Transport of materials within the cell is usually carried out by microtubules and motor proteins.
