The maximum non zero values for DOUBLE is . . . . . . . .

Answer: Option B

This question is about the maximum values that a DOUBLE data type can hold in MySQL.
Think of DOUBLE as a type that can store really big numbers, both positive and negative.
Let's break down the options:
* Option A: ±1.7976931348623157E+307 * Option B: ±1.7976931348623157E+308 * Option C: ±1.7976931348623157E+306 * Option D: ±1.7976931348623157E+305
The 'E' in the options stands for 'exponent', which means we're dealing with very large numbers.
The correct answer is Option B: ±1.7976931348623157E+308. This represents the largest possible value that a DOUBLE can store in MySQL.
So, if you need to store super big numbers in your MySQL database, you can use the DOUBLE data type and it can hold values up to ±1.7976931348623157E+308.
