B. Rangka
Explanation
The correct answer is "Rangka". The other options, which are "Tulang", "Otot", and "Sendi", all contribute to the human skeletal system and are involved in the movement of the body. The skeletal system is responsible for providing support, protecting organs, and facilitating movement through the coordination of bones, muscles, and joints. However, "Rangka" is not a separate component but rather another term for the skeletal system itself. Therefore, it does not fit the criteria of being a component that makes up the human skeletal system.

Correct Answer
C. Kanalikuli, Osteosit, Saluran Harvers
Explanation
The correct answer is "Kanalikuli, Osteosit, Saluran Harvers". This is because kanalikuli refers to the tiny canals that connect the lacunae (spaces) within the bone, allowing for the exchange of nutrients and waste products. Osteosit refers to the mature bone cells that are found within the lacunae. Saluran Harvers, also known as Haversian canals, are larger channels that contain blood vessels and nerves, running parallel to the bone's long axis. Therefore, the correct order is kanalikuli, osteosit, and saluran Harvers.
