The REAL type is synonym for . . . . . . . .

This question is about data types in MySQL. Data types tell the database what kind of information we're storing.

The REAL data type is used for storing decimal numbers (numbers with a decimal point).

Let's look at the options:

Option A: FLOAT - FLOAT is also used for storing decimal numbers, and it's a synonym for REAL.

Option B: INT - INT is used for storing whole numbers (integers).

Option C: DOUBLE - DOUBLE is another data type for storing decimal numbers, but it allows for larger and more precise values than REAL.

Option D: BIT - BIT is used for storing single bits of data, either 0 or 1.

Therefore, the correct answer is Option A: FLOAT. REAL and FLOAT are essentially the same data type in MySQL. They both store decimal numbers.
