Values in the first column of a "table_array" are most similar to " a key database concept.
Option A is correct.
What is a key?A key is a unique identifier for a record in a database. Similarly, the first column of a table_array in a lookup function is used to match a lookup_value and return a corresponding value from another column. For example, in the table below, the first column is a key for each student's name and grade.
Name Grade Subject
Alice A Math
Bob B Science
Charlie C English
If we use the lookup function =VLOOKUP(""Bob"", A1:C3, 2, FALSE), we are looking for the value ""Bob"" in the first column of the table_array A1:C3, and returning the value from the second column, which is Bob's grade.
The result is B. The FALSE argument indicates that we want an exact match for the lookup_value. If we use TRUE instead, the lookup function will return an approximate match, which may not be accurate if the first column is not sorted in ascending order."

After executing the given 'for loop' i.e. 'for (int itemCount : itemStock) {
