Absolute advantage (lower absolute labour hours per unit):
- Glass Bottle: India (2hrs) < Bangladesh (3hrs) → India has absolute advantage.
- Ceramic Plate: India (3hrs) < Bangladesh (9hrs) → India has absolute advantage here too.
India has an absolute advantage in both goods — this is a case where one country is more efficient at everything, which is exactly why comparative advantage (not absolute advantage) is what actually determines the pattern of beneficial trade.
Opportunity costs (comparative advantage — lower opportunity cost wins):
- India's opportunity cost of 1 Glass Bottle = 2/3≈0.67 Ceramic Plates.
- Bangladesh's opportunity cost of 1 Glass Bottle = 3/9≈0.33 Ceramic Plates.
Bangladesh has the lower opportunity cost for Glass Bottles (0.33 < 0.67), so Bangladesh has comparative advantage in Glass Bottles, meaning India has comparative disadvantage in Glass Bottles.
Correspondingly, India's opportunity cost of 1 Ceramic Plate = 3/2=1.5 Glass Bottles, versus Bangladesh's 9/3=3 Glass Bottles — India's opportunity cost is lower, so India has comparative advantage in Ceramic Plates.
Putting it together: India has absolute advantage in Glass Bottles AND comparative disadvantage in Glass Bottles — matches (A). India also has absolute advantage in Ceramic Plates AND comparative disadvantage in Glass Bottles (equivalently, comparative advantage in Ceramic Plates) — matches (C), which correctly pairs 'absolute advantage in Ceramic Plate' with 'comparative disadvantage in Glass Bottle' (the complementary, correctly-matched statement).
(B) is incorrect because India does NOT have a comparative disadvantage in Ceramic Plate — it has a comparative advantage there. (D) is incorrect because it pairs Glass Bottle absolute advantage with Ceramic Plate comparative disadvantage, which misstates India's actual comparative disadvantage (which is in Glass Bottle, not Ceramic Plate).
Therefore the correct statements are (A) and (C).
