Explanation:

- To find the average of natural numbers from 1 to 43, use the formula for the average of consecutive numbers, which is \((\text{first number} + \text{last number}) / 2\).

- Here, the formula is \((1 + 43) / 2 = 44 / 2 = 22\).

- Now, let's evaluate the options:

- Option 1: 32 - This option is incorrect because it doesn't equal the average calculated.

- Option 2: 22 - This is the correct answer. It matches the average we calculated, which is \(22\).

- Option 3: 44 - This option is also incorrect because it's the sum but not the average.

- Option 4: 43 - This option is incorrect since it's the last number, not the average.

- The correct choice is option 2.

Correct Answer: Option 2 - 22
