D
None of the above
Explanation: 

Detailed explanation-1: -A food bolus is a semi-solid mass of food (most often meat) not associated with a hard or sharp foreign body. If you suspect that that there may be a hard or sharp foreign body, proceed as for a ingested hard foreign body.

Detailed explanation-2: -In digestion, a bolus (from Latin bolus, “ball") is a mass of food that (with animals that can chew) has been chewed at the point of swallowing. Under normal circumstances, the bolus then travels down the esophagus to the stomach for digestion.

Detailed explanation-3: -Ingestion. The first activity of the digestive system is to take in food through the mouth. This process, called ingestion, has to take place before anything else can happen.

Detailed explanation-4: -bolus, food that has been chewed and mixed in the mouth with saliva. Chewing helps to reduce food particles to a size readily swallowed; saliva adds digestive enzymes, water, and mucus that help chemically to reduce food particles, hydrate them for taste, and lubricate them for easy swallowing.
