Explanation

To solve the question "The disaccharide present in milk is," we can follow these steps:

### Step 1: Identify the options given
The options provided are:
- A) Amylose
- B) Lactose
- C) Sucrose
- D) Glucose

### Step 2: Analyze each option
- **Amylose**: This is a polysaccharide, not a disaccharide. It is a component of starch made up of many glucose units.
- **Lactose**: This is a disaccharide that is specifically found in milk. It is composed of two monosaccharides: glucose and galactose.
- **Sucrose**: This is also a disaccharide, made up of glucose and fructose, but it is not found in milk.
- **Glucose**: This is a monosaccharide, not a disaccharide.

### Step 3: Determine the correct answer
Among the options, lactose (option B) is the only disaccharide that is present in milk. It is formed from the combination of glucose and galactose through a glycosidic linkage.

### Final Answer
The disaccharide present in milk is **Lactose** (Option B).
