To determine the correct answer to the multiple-choice question regarding the space inside the diaphysis that is filled with yellow bone marrow, we can analyze each option provided:

1. Periosteum: This is a dense layer of vascular connective tissue that envelops the bones except at the surfaces of the joints. It does not contain yellow bone marrow.

2. Medullary cavity: This is the central cavity of bone shafts where yellow bone marrow is stored. It is specifically located in the diaphysis of long bones.

3. Endosteum: This is a thin membrane lining the medullary cavity. While it is related to the cavity, it does not contain marrow itself.

4. Central canal: Also known as the Haversian canal, this contains blood vessels and nerves but does not contain yellow bone marrow.

The space inside the diaphysis that is filled with yellow bone marrow is the Medullary cavity.
