A certain person eats boiled potato, one of the food component in it is

Options

A. lactose which is indigestible
B. starch which does not digested
C. cellulose which is digested by intestinal cellulose
D. DNA which gets digested by pancreatic DNAase.

Explanation

To solve the question regarding the food components in boiled potatoes, we will analyze the options provided and determine which one is a component of boiled potatoes.

### Step-by-Step Solution:

1. **Understanding the Composition of Boiled Potatoes**:
- Boiled potatoes primarily consist of carbohydrates, proteins, and some vitamins and minerals. The main carbohydrate in potatoes is starch.

2. **Analyzing the Options**:
- **Option 1: Lactose**
- Lactose is a sugar found in milk. It is not present in potatoes, so this option is incorrect.

- **Option 2: Starch**
- Starch is indeed a major component of potatoes. It is a polysaccharide that gets partially digested in the mouth by salivary amylase. Therefore, this option is also a valid component of boiled potatoes.

- **Option 3: Cellulose**
- Cellulose is a structural component of plant cell walls. Humans lack the enzyme cellulase to digest cellulose, so while it is present in potatoes, it is not digestible by humans. Thus, this option is not correct in the context of digestible components.

- **Option 4: DNA**
- DNA is present in the cells of all living organisms, including potatoes. It is digested by pancreatic DNAs in the human digestive system. Thus, this option is also a valid component of boiled potatoes.

3. **Conclusion**:
- Among the options, starch and DNA are both components of boiled potatoes. However, since the question asks for "one of the food components," the most relevant answer considering digestion would be **starch**, as it is a significant carbohydrate that is partially digestible.

### Final Answer:
- One of the food components in boiled potato is **starch**.
