The correct answer is Choice A.Choice A rationaleHirschsprung’s disease is characterized by inadequate motility of part of the intestine, resulting in a mechanical obstruction. This condition is caused by the absence of ganglion cells in the affected segment of the intestine, leading to a lack of peristalsis and subsequent obstruction.Choice B rationaleEncopresis is a condition characterized by the repeated passage of feces into inappropriate places, such as clothing or the floor. It is not associated with inadequate motility of the intestine or mechanical obstruction.Choice C rationalePyloric stenosis is a condition characterized by the narrowing of the pylorus, which leads to obstruction of the passage of food from the stomach to the small intestine.
