This question is incomplete because the options are missing; here is the complete question:

The nursing instructor is teaching a class on the types of joints. Which statement by the student nurse about synovial joints indicates effective learning?

A. "Synovial joints are immovable and united by cartilage."

B. "Synovial joints are freely movable and lined with synovial membranes."

C. "Synovial joints are slightly movable, and the bones are joined with cartilage."

D. "Synovial joints do not allow opposing surfaces to slide against one another."

The correct answer to this question is B. "Synovial joints are freely movable and lined with synovial membranes."

Explanation:

In anatomy, synovial joints include joints such as the one of the knee or the hip that are surrounded by synovial fluid. Also, due to the fluid, these joints have more movement than other joints. Besides this, all synovial joints include synovial membranes that produce the fluid in the joints and aligns structures in the joint such as tendons. In this context, if a practitioner learned correctly about this type of joints he would know these are freely movable and lined with synovial membranes (option B.)
