Step 1: Analyzing Each Sweet and Its Regional Origin:
We will systematically analyze the cultural and geographic origin of each traditional Indian sweet listed:
• Doda (or Dhoda): This is a highly popular, rich, grain-textured, fudge-like sweet made of milk, liquid glucose, sugar, and dry fruits. It originated in the Punjab region, which is situated in North India. Thus, 1 matches with (iii).
• Mysore Pak: Invented in the royal kitchens of the Mysore Palace in Karnataka, this sweet is made from chickpea flour (besan), pure ghee, and sugar. Karnataka is located in South India. Thus, 2 matches with (iv).
• Bhapa Doi: Literally translating to “steamed yogurt”, this is a classic, delicate, baked/steamed sweetened yogurt dessert from West Bengal, which lies in East India. Thus, 3 matches with (i).
• Dodol: This is a sweet, dark, jelly-like, chewy dessert made of coconut milk, palm jaggery, and rice/ragi flour. It is a traditional festive sweet of Goa (and coastal regions), which is located in West India. Thus, 4 matches with (ii).
Step 2: Compiling the Matchings:
$$\text{1} \to \text{(iii)}, \quad \text{2} \to \text{(iv)}, \quad \text{3} \to \text{(i)}, \quad \text{4} \to \text{(ii)}$$
This sequence corresponds precisely to Option (D).
