Explanation:

Let's analyze the given equation with each option to identify the correct one:

- Original equation: $60\times 4+9÷3-8=34$

Option 1: Swap + and -

- New equation: $60\times 4-9÷3+8$

- Simplified: $240-3+8=245$

- This does not equal 34.

Option 2: Swap ÷ and +

- New equation: $60\times 4÷9+3-8$

- Simplified: $240÷9+3-8=36\text{(approx)}$

- This does not equal 34.

Option 3: Swap + and ×

- New equation: $60+4\times 9÷3-8$

- Simplified: $60+12-8=64$

- This does not equal 34.

Option 4: Swap + and ×

- New equation: $60+4\times 9÷3-8$

- Simplified: $60+12-8=64$

- This is a repeat of Option 3 and incorrect.

Correct Answer: None of the options given directly fix the equation because of a repeat in the analysis, but examining the statement with correction leads us to:

Subtract 60 - implies incorrect understanding or repeat comparison occurred. Upon further reflection, the equation and analysis are error-involved selector picks:

Option 3: Swap + and × was tested again and breakdown repeat formula assignment missing.

```Try evaluation again:

- $60\times 4÷9+3-8=4$

Checking initial repeat solution proves unsatisfactory.
