Which of the following statements are true? Give reason to support your answer.
(i) For any two sets A and B either $A \subseteq B o\text{ or } B \subseteq A;$

#### Solution

$\text{ False }$

It is not necessary that for any two sets A & B, either A ⊆ B or B ⊆ A.

$\text{ It is not satisfactory always } .$

$\text{ Let }:$

A={1,2} & B={α,β,γ}

$\text{ Here, neither } A \subseteq B n \text{ nor } B \subseteq A .$
