Which cytoskeletal components provide strength and support for the cell?

Explanation:
Microfilaments provide the strength and support that help the cell maintain its shape and resist deformation. These actin-based filaments form a dense network just beneath the plasma membrane—the cell cortex—giving the cell tensile strength and helping it resist pulling forces. They also enable shape changes and movement by interacting with myosin to generate contractile forces. The other structures listed aren’t primarily responsible for structural support: organelles are functional compartments inside the cell, inclusions are storage materials, and ribosomes are the machinery for protein synthesis. So the microfilaments are the components that best provide the cell’s strength and structural integrity.
