Explanation:
Detailed explanation-1: -Cardiac muscle is (c) striated, branching, with gap junctions within intercalated discs. These gap junctions allow the cardiomyocytes to synchronize their activity and consequently, the heart beat.
Detailed explanation-2: -Cardiac muscles contain intercalated discs and branching fibers. Intercalated discs support synchronized contraction of cardiac muscle tissue.
Detailed explanation-3: -Cardiac muscle cells (cardiomyocytes) are striated, branched, contain many mitochondria, and are under involuntary control. Each myocyte contains a single, centrally located nucleus and is surrounded by a cell membrane known as the sarcolemma.
