Which SQL function is used to count the number of rows in a table?

The COUNT() function in SQL is specifically designed to return the number of rows that match a specified condition. This function can be used to count all rows in a table, rows that satisfy a particular condition, or rows for a specific column. It is one of the aggregate functions in SQL that helps in summarizing data. Option A (SUM()) is incorrect because SUM() is used to calculate the total of a numeric column, not to count rows. Option C (AVG()) is incorrect as it calculates the average value of a numeric column. Option D (MAX()) is incorrect because it returns the maximum value in a specified column. Option E (MIN()) is incorrect since it returns the minimum value in a specified column.
