A
Occluding junctions
B
Tight junctions
C
Desmosomes
D
Gap junctions
E
Connexons
Explanation: 

Detailed explanation-1: -Gap junctions within the intercalated disks allow impulses to spread from one cardiac muscle cell to another, allowing sodium, potassium, and calcium ions to flow between adjacent cells, propagating the action potential, and ensuring coordinated contractions.

Detailed explanation-2: -Cardiac Muscle. Intercalated discs are part of the cardiac muscle sarcolemma and they contain gap junctions and desmosomes.

Detailed explanation-3: -Desmosomes. Several desmosomes (also called the macula adherens) are located along each ICD. Gap junctions. Fascia adherens. Transitional junction.
