The correct answer is B. Ingestion.
To arrive at the correct answer, we can analyze each option:
A. Digestion: Digestion is the process of breaking down food into smaller molecules for absorption. While this is a crucial function of the digestive system, it comes after the initial activity.
B. Ingestion: Ingestion refers to the process of taking food into the body through the mouth. This is the first step in the digestive process when we consume food.
C. Movement: Movement plays a role in the digestive system to propel food through the digestive tract. While it is an important activity, it occurs after ingestion.
D. Absorption: Absorption occurs after digestion, where the digested molecules are taken up by the body and transported to various cells and tissues. Hence, it is not the first activity of the digestive system.
Thus, the correct answer is B. Ingestion.
