Answer

To solve the question about the smallest natural number, let's go through the steps:

### Step 1: Understand what natural numbers are
Natural numbers are the set of positive integers that start from 1 and go on indefinitely. The sequence of natural numbers is: 1, 2, 3, 4, 5, and so on.

### Step 2: Identify the options given
The options provided in the question are:
(i) 0
(ii) 1
(iii) 2
(iv) Not defined

### Step 3: Determine the smallest natural number
Since natural numbers start from 1, we can conclude that:
- 0 is not a natural number.
- 1 is the first and smallest natural number.
- 2 is larger than 1.
- "Not defined" does not apply here as we have a clear definition of natural numbers.

### Step 4: Choose the correct answer
Based on our understanding, the smallest natural number is 1. Therefore, the correct answer is option (ii) 1.

### Final Answer
The smallest natural number is **1** (option ii).
