दिखाइए कि यदि $A \subset B ,$ तो $C - B \subset C - A$

Option A
Option B
Option C
Option D

Solution

Let $A \subset B$

To show: $C-B \subset C-A$

Let $x \in C-B$

$\Rightarrow x \in C$ and $x \notin B$

$\Rightarrow x \in C$ and $x \notin A[A \subset B]$

$\Rightarrow x \in C-A$

$\therefore C-B \subset C-A$
