Non-metals want electrons, metals give them away; check each statement against that one picture.

1. The core contrast. Non-metals sit on the right of the periodic table and hold on to electrons tightly. Metals sit on the left and lose electrons easily. Every statement here is a test of that difference.

   Statement	What is actually true	Verdict
   (A) Non-metals have higher electronegativity	Non-metals attract bonding electrons strongly, for example F 4.0 against Na 0.9	Correct
   (B) Non-metals have lower ionisation enthalpy	Non-metals have higher ionisation enthalpy, which is why they do not lose electrons easily	Wrong
   (C) Reactive metal + reactive non-metal gives ionic compounds	The large electronegativity difference transfers electrons fully, as in NaCl and CsF	Correct
   (D) Non-metal oxides are basic	They are acidic, for example SO₃ and P₄O₁₀, or neutral, for example CO and N₂O	Wrong
   (E) Metal oxides are acidic or neutral	They are basic, for example Na₂O and CaO	Wrong

2. Oxides swapped. Statements (D) and (E) describe the two kinds of oxide the wrong way round. A metal oxide forms a base in water. A non-metal oxide forms an acid in water, or does not react at all.
3. So. Only (A) and (C) are correct, which is option (d).

The idea to keep. Going left to right, metallic character falls while ionisation enthalpy, electronegativity and the acidity of the oxides all rise. Metal oxides are basic and non-metal oxides are acidic.
