This corrct answer A
Step-by-step explanation:
The question you asked relates to the human digestive system and how it processes food, which makes it a topic under the subject of Health. Specifically, it falls into the middle school level of education.
The illustration with the car parts is a metaphor for how your digestive system breaks down the food you eat. When you consume food, such as a bacon, lettuce, and tomato sandwich, the journey begins in your mouth. This is where physical digestion takes place with the help of your teeth and tongue, cutting and grinding the food into smaller pieces.
Then, your food tube, known as the esophagus, transports the food to your stomach and intestines where chemical digestion occurs. Enzymes and acids break down the food, and nutrients are absorbed through the walls of the intestines.
The waste left behind, after absorption, is compacted and eventually excreted through your anus. This process is analogous to the car being stripped of its parts and the unusable pieces being discarded, as explained in your question.
