We have to identify the irrational number.

An irrational number is a number that can not be expressed as a fraction.

The first option is the square root of 0 which is equal to 0. It is an integer so it can be expressed as a fraction.

Then, it is not an irrational number.

The second option is the square root of 3. This does not have a solution that can be expressed as a fraction or a number with a finite number of decimals.

Then, it can be considered an irrational number.

The third option is a periodic decimal. They can be expressed as fractions so they are not irrational numbers.

the fourth option is a negative decimal number, which can be expressed as decimal, like -19/100. Then, it is not an irrational number.

Answer: the only irrational number is √3 [Option B]
