Answer 32. The correct option is B: striated involuntary. Banding pattern is due to the presence of myofibrils and if it is not controlled then it is involuntary in nature.

Answer 33. The correct option is B. Smooth muscles. These muscles are present in digestive tract and the movement is caused by contractions and relaxation of smooth muscles. This phenomenon is called 'peristalsis'.
