**Question 12:**

Which argument is optional for the HLOOKUP function?  

**Answer:**

- **A.** Lookup value  
- **B.** Table array  
- **C.** Column index number  
- **D.** Range lookup  

---

**Explanation:**

The HLOOKUP function in Excel is used to look up data in a row-wise manner. The syntax for the HLOOKUP function is:

`HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])`

In this function:
- **Lookup value**: The value to search for in the first row of the table array. (Required)
- **Table array**: The table of information wherein data is looked up. (Required)
- **Row index number**: The row number in the table array from which to retrieve a value. (Required)
- **Range lookup**: A logical value that specifies whether you want an exact match or an approximate match. This argument is optional. If omitted, it defaults to TRUE (approximate match).

### Question 13: Lookup Function Error Handling

**Question:**
What displays when the range lookup in a lookup function is False and an exact match is not located in the table array?

**Answer Options:**
A. 
- \( \circ \) 0

B. 
- \( \circ \) \#DIV/0!

C. 
- \( \circ \) \#N/A

D. 
- \( \circ \) A blank space

**Explanation:**
When using a lookup function (such as `VLOOKUP` or `HLOOKUP`) in spreadsheet software like Microsoft Excel or Google Sheets, with the range lookup parameter set to `False`, the function will search for an exact match in the specified table array. If an exact match is not found, the function returns the `#N/A` error. Thus, the correct answer is:

**C. \( \circ \) \#N/A**
