Step-by-Step Solution
Solution:
Step 1: Understand the condition requirements
You want to check ifstatusis eithertrueORnil, so use logical OR (||).Step 2: Analyze each option
if status == true || status == nil usesstatus == true || status == nil, which matches the requirement. if status == true && status == nil uses AND, which can never be true for both at once. if status || nil is incorrect syntax and logic. if status != false checks ifstatusis not false, which includes other values too.Final Answer:
if status == true || status == nil -> Option AQuick Check:
Use OR (||) to check either condition [OK]

- Using && instead of ||
- Confusing != false with true or nil
- Writing invalid condition syntax
