Question:

If $x, y ∈R$ then match List-I with List-II

List-I

List-II

(A) $|x|< |y|$

(1) iff $x^2 > y^2$

(B) $|x|> |y|$

(11) iff $x^2≤ y^2$

(C) $|x| ≤|y|$

(III) iff $x^2 <y^2$

(D) $|x| ≥ |y|$

(IV) iff $x^2≥ y^2$

Choose the correct answer from the options given below:

Options:

(A)-(III), (B)-(II), (C)-(I), (D)-(IV)

(A)-(III), (B)-(I), (C)-(II), (D)-(IV)

(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

(A)-(II), (B)-(II), (C)-(IV), (D)-(I)

Correct Answer:

(A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Explanation:

The correct answer is Option (2) → (A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Given:

(A) |x| < |y|

Property: |x| < |y| iff x² < y² → (A) matches (III)

(B) |x| > |y|

Property: |x| > |y| iff x² > y² → (B) matches (I)

(C) |x| ≤ |y|

Property: |x| ≤ |y| iff x² ≤ y² → (C) matches (II)

(D) |x| ≥ |y|

Property: |x| ≥ |y| iff x² ≥ y² → (D) matches (IV)
