Afalse
Bnil
Ctrue

Step-by-Step Solution
Solution:

  1. Step 1: Understand operator precedence in Swift

    Logical AND (&&) has higher precedence than logical OR (||), so evaluate true && false first, which is false.

  2. Step 2: Evaluate the full expression

    Now the expression becomes false || true, which evaluates to true.

  3. Final Answer:

    true -> Option C

  4. Quick Check:

    Operator precedence: && before || = true [OK]
Quick Trick: && is evaluated before || in Swift expressions [OK]
Common Mistakes:
  • Evaluating || before &&
  • Assuming syntax error
  • Confusing true/false values
