उत्तर

This statement is False.

Explanation:

Set A = {0, 1, 2} - A is a finite set of 3 integers.

Set B = {x ∈ ℝ | 0 ≤ x ≤ 2} B includes all real numbers from 0 to 2. That means:

B = {x ∈ R ∣ 0 ≤ x ≤ 2}

which includes:

  • All whole numbers: 0, 1, 2
  • All decimal values: 0.1, 0.5, 1.25, 1.999, etc.
  • All irrational values: √2, π/2, etc.

The image wrongly claims that: 

B = {0, 1, 2}

That is only true if B is defined as: B = {x ∈ Z ∣ 0 ≤ x ≤ 2}

(where Z = set of integers)

But the question clearly states: 

x ∈ R — set of real numbers, not just integers.

So B is an infinite set, while A is a finite set.

Sets A and B are not equal. Hence, the statement is False.
