A Simple IF evaluates one Boolean condition and returns one of two results (true/false or yes/no), so it's ideal when eligibility or output depends on a single test. In spreadsheet syntax the pattern is IF(condition, value_if_true, value_if_false).

Relevant knowledge points:
- A Simple IF handles one decision point (binary outcome).
- Aggregation tasks (counting, summing) use functions like COUNT, SUM or pivot tables, not a single IF.
- Multi-tier decisions (multiple discount levels) require nested IFs, SWITCH, or lookup tables.
- Multiple independent criteria require combining tests (AND/OR) or a more complex logical structure.

Step-by-step reasoning with an example:
1. Define the single condition: e.g., "purchase_amount >= 50" for coupon eligibility.
2. Evaluate the condition for a given customer:
   - If purchase_amount is 65, test 65 >= 50 is TRUE.
   - If purchase_amount is 30, test 30 >= 50 is FALSE.
3. Apply the IF formula: IF(purchase_amount >= 50, "Eligible", "Not Eligible").
   - For 65 → returns "Eligible".
   - For 30 → returns "Not Eligible".
4. This flow uses one clear binary decision — exactly what a Simple IF is for.

Why the correct option fits:
- "to determine whether a customer was eligible for a coupon or not" is a single yes/no test (meets threshold or not), so a Simple IF cleanly implements it.

Why the other options are incorrect:
- Counting quantity of units sold: use COUNT or SUMPRODUCT, not a single IF for aggregation.
- Determining SUM of an item sold last month: use SUM or SUMIFS.
- Determining what discount an employee gets with 5 levels: requires nested IFs, SWITCH, or lookup table (not a single simple IF).
- Counting number of people attending: use COUNT.
- Determining whether an employee met 2 criteria (Full Time and 30+ hours): requires combining conditions with AND or a compound/nested logic, so it’s more than a single simple IF scenario.

Conclusion: The best real-world example for a Simple IF is to determine whether a customer was eligible for a coupon or not, which matches the provided answer.
