Solution

The correct option is C $(A) \to q; (B) \to s; (C) \to r, (D) \to p$
$(A) \to q; (B) \to s; (C) \to r; (D) \to p$
$2 x + y = 7 L . H . S = 2 x + 7 = 2 (1) + 5 = 7 = R . H . S . ∴ (A) \to q$

$x - 2 y = 4 L . H . S = x - 2 y = 4 - 2 (0) = 4 = R . H . S ∴ (B) \to s$

$x - 4 y = 0 L . H . S . = x - 4 y = 0 - 4 (0) = 0 = R . H . S . ∴ (C) \to r$

$p x + y = 9 L . H . S = p x + y = p (0) + 9 = 9 = R . H . S . ∴ (D) \to p$
