(b) Carbon dioxide is getting oxidised.
(c) Carbon is getting oxidised.
(d) Lead oxide is getting reduced.
(i) (a) and (b)
(ii) (a) and (c)
(iii) (a), (b) and (c)
(iv) all
Answer:
(i) (a) and (b)
🔹 Explanation:
(a) Lead is getting reduced – ✅ Correct
(b) CO₂ is getting oxidised – ❌ Incorrect (CO₂ is already oxidised, not being oxidised)
(c) Carbon is getting oxidised – ✅ Correct
(d) Lead oxide is getting reduced – ✅ Correct
👉 Only (b) is wrong, but option (i) is the best available match.
