Correct answer: C

Option (3) is the correct answer as cardiac muscle fibres possess communication junctions (intercalated discs) at some fusion points that allow the cells to contract as unit, i.e., when one cell receives a signal to contract, its neighbours are also stimulated to contract.

Option (1) is incorrect as smooth muscle fibres are uninucleated.

Option (2) is incorrect as skeletal muscle fibres are multinucleated.

Option (4) is incorrect as the wall of blood vessels are made up of simple squamous epithelium.
