Compound 1: P = 50 g, Q = 50 g → EF = P : Q = 1:1 → P Q

Compound 2: P = 44.4 g, Q = 55.6 g → EF ≈ P₄Q₅

]Compound 3: P = 40 g, Q = 60 g → EF ≈ P₃Q₄

Step 1: Comparing 2 & 3 → law of multiple proportions satisfied → (A) correct
Step 2: Comparing 1 & 2 → small whole-number ratio → (C) correct
Step 3: If atomic weights P = 70, Q = 35 → compound 1: moles P:Q = 50/70 : 50/35 = 5:10 = 1:2 → EF = P Q₂ → (D) correct
