What is the datatype for single precision floating point number?

Answer: Option A

This question is asking about how MySQL stores numbers with decimal points.

Think of it like this:

* FLOAT is for numbers that don't need super high precision (like 3.14159). They are like small, quick calculators.
* DOUBLE is for numbers that need extra accuracy, like for scientific calculations (think really long decimals). They are like high-powered calculators.
* INT and BIGINT are for whole numbers (no decimal points) that are small (INT) or big (BIGINT).

So, the answer is Option A: FLOAT.
