Digestion of proteins begins in the ((i))rarr` and digestion of polysaccharides begins in the `((ii))rarr`.

Options

A. mouth stomach
B. stomach small intestine
C. stomach mouth
D. stomach stomach

Explanation

To solve the question regarding where the digestion of proteins and polysaccharides begins, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Identify the Digestion of Proteins**:
- Digestion of proteins primarily occurs in the stomach. The stomach secretes gastric juices, which contain enzymes like pepsin that break down proteins into smaller peptides.

2. **Identify the Digestion of Polysaccharides**:
- The digestion of polysaccharides (complex carbohydrates) begins in the mouth. In the mouth, the enzyme salivary amylase is secreted in saliva, which starts breaking down starches (a type of polysaccharide) into simpler sugars.

3. **Combine the Answers**:
- From the above points, we can conclude:
- (i) Digestion of proteins begins in the **stomach**.
- (ii) Digestion of polysaccharides begins in the **mouth**.

### Final Answer:
- (i) Stomach
- (ii) Mouth
