Final answer:

Striated muscles include skeletal muscles, which are voluntary and can be controlled at will, such as muscles of the arms, and cardiac muscle found in the heart, which is also striated but operates involuntarily. Therefore, both muscle of the heart and muscles of the arms are examples of striated muscles. Muscle of blood vessels is incorrect as it is composed of smooth muscle.

Step-by-step explanation:

Striated muscles are characterized by their appearance under a microscope - they exhibit a pattern of light and dark bands, known as striations. There are two types of striated muscles: skeletal and cardiac muscle. Skeletal muscles are also known as voluntary muscles because they can be controlled by an individual's will. They are responsible for body movements and are attached to bones. Cardiac muscle is the muscle of the heart, and while it is striated, it operates involuntarily. Smooth muscles, found in organs such as blood vessels and the digestive system, are not striated and are involuntary.

Therefore, the correct answers from the options provided are:

Muscle of the heart - because cardiac muscle is striated.

Muscles of the arms - because these are skeletal muscles, which are also striated.

Voluntary muscles - since voluntary muscles are skeletal muscles, they are also striated.

Muscle of the blood vessels would not be a correct answer, as the muscle found within blood vessels is smooth muscle, which is not striated.
