One of the different amino acids which can be synthesised in the body is:

Options

A. Alanine
B. Lysine
C. Valine
D. Histidine

Explanation

To answer the question "One of the different amino acids which can be synthesized in the body is:", we will follow these steps:

### Step 1: Understand the Classification of Amino Acids
Amino acids are classified into two main categories:
- **Essential Amino Acids**: These cannot be synthesized by the body and must be obtained through diet.
- **Non-Essential Amino Acids**: These can be synthesized by the body.

### Step 2: Identify Examples of Each Category
- **Essential Amino Acids**: Examples include lysine, valine, and histidine.
- **Non-Essential Amino Acids**: Examples include alanine, glycine, and tyrosine.

### Step 3: Analyze the Question
The question asks for an amino acid that can be synthesized in the body. This indicates we are looking for a non-essential amino acid.

### Step 4: Select the Correct Answer
From the examples provided:
- Alanine is a non-essential amino acid and can be synthesized in the body.
- Lysine, valine, and histidine are essential amino acids and cannot be synthesized.

Thus, the answer to the question is **alanine**.

### Final Answer
One of the different amino acids which can be synthesized in the body is **alanine**.
