 Line 1: IF (a = 0)
 Line 2: {
 Line 3: b ← a + 10
 Line 4: }
 Line 5: ELSE
 Line 6: {
 Line 7: b ← a + 2O
 Line 8: }
 Which of the following changes will NOT affect the results when the code segment is executed?
(A)Changing line 3 to b ← 10 (B)Changing line 3 to a ← b + 10 (C)Changing line 7 to b ← 20 (D)Changing line 7 to a ← b + 10
