As we learnt 

 

EMPTY SET -

 

A set which does not contain any element is called the empty set or the null set or the void set.

- wherein

eg. {1<x<2, x is a natural number}

 

 x^{4}-1=0\Rightarrow \left ( x^{2}-1 \right )\left ( x^{2} +1\right )= 0\: \: which\: \: gives\: \: x=\pm 1

 


Option 1)

Real Solutions of x^{2}+2x+3=0

Option 2)

lmaginary Solutions of x^{2}+3x+2=0

Option 3)

Real Solutions of x^{4}+x^{2}+1=0

Option 4)
