Covers the external surface of the epiphyses and decreases friction at joint surfaces
A
Periosteum
B
Red Bone Marrow
C
Medullary Cavity
D
Articular Cartilage
E
Epiphyseal plate
Explanation: 

Detailed explanation-1: –The epiphyses are covered by a thin layer of compact tissue. Their interior contains spongy bones and red marrow. On its outer surface, the articular portion of the epiphysis is coated with hyaline cartilage.

Detailed explanation-2: -In this region, the epiphyses are covered with articular cartilage, a thin layer of hyaline cartilage that reduces friction and acts as a shock absorber. Figure 6.32 – Periosteum and Endosteum: The periosteum forms the outer surface of bone, and the endosteum lines the medullary cavity.

Detailed explanation-3: -Hyaline cartilage at the ends of your bones is sometimes referred to as articular cartilage. Hyaline cartilage is slippery and smooth which helps your bones move smoothly past each other in your joints.
