The function returning an array of row values is . . . . . . . .

Answer: Option A

This question is asking about a function in MySQL that gets data from a database table and returns it as an array. Arrays are like lists that can hold multiple values.
Let's break down the options:
Option A: fetchrow_array(): This option is incorrect. The function fetchrow_array() is not a standard MySQL function.
Option B: fetchrow_arrayref(): This option is incorrect. The function fetchrow_arrayref() is not a standard MySQL function.
Option C: fetch(): This option is partially correct. The fetch() function is commonly used in MySQL to retrieve data from a query. However, it doesn't specifically return an array of row values. It depends on the specific database library you're using.
Option D: fetchrow_hashref(): This option is incorrect. The function fetchrow_hashref() is not a standard MySQL function.
Therefore, the correct answer is none of the above.
MySQL doesn't have a built-in function that directly returns an array of row values.
To retrieve data as an array, you typically need to use a database library or API that provides functionality for this.
