The part of a long bone that is directly covered with articular cartilage is the
A
diaphysis.
B
endosteum.
C
epiphysis.
D
periosteum.
Explanation: 

Detailed explanation-1: -Epiphysis is the end part of a long bone and it is covered with articular cartilage. 2. Hyaline cartilage that is present on the ends of ones in synovial joints is known as articular cartilage.

Detailed explanation-2: -Articular cartilage is a white elastic tissue that allows bones to glide smoothly against each other. It covers the end of the femur and acetabulum. The function of articular cartilage is to absorb shock and provide an extremely smooth surface to make movement easier.

Detailed explanation-3: -At the joint, the epiphysis is covered with articular cartilage; below that covering is a zone similar to the epiphyseal plate, known as subchondral bone. Structure of a long bone, with epiphysis labeled at top and bottom. The epiphysis is filled with red bone marrow, which produces erythrocytes (red blood cells).

Detailed explanation-4: -epiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone.

Detailed explanation-5: -Epiphyseal cartilage is hyaline cartilage tissue with a gelatinous texture, and it is responsible for the longitudinal growth of the long bones in birds and mammals. It is located between the epiphysis and the diaphysis. Epiphyseal cartilage also is called a growth plate or physis.
