Consider the code segment below.

Line 1: IF (b ≠ 0)
Line 2: {
Line 3: a ← a/b
Line 4: }
Line 5: ELSE
Line 6: {
Line 7: a ← a*b
Line 8: }
```

Which of the following changes will NOT affect the results when the code segment is executed?

a) Changing Line 3 to `a ← a + b`
b) Changing Line 7 to `a ← a - b`
c) Changing Line 2 to `IF (b = 0)`
d) Changing Line 6 to `a ← a/b`
