To easily solve matching questions, look for highly specific terms first: "HTST" is always linked to pasteurization, and "Freeze drying" is the only drying process operating below water's triple point.
Step 1: Sort the four List-I items by the type of operation they describe. The list mixes agricultural processing operations, a physical property, a piece of separation machinery and a transport mechanism, so the first step is to recognise which broad category each entry of List-I falls under before trying to pick a partner from List-II. Step 2: Match each category to its natural counterpart in List-II. A processing operation pairs with the equipment that performs it, a physical property pairs with the parameter or test used to measure it, and a transport mechanism pairs with the specific conveying device that realises it. Working item by item this way narrows the four possible pairs down to one set. Step 3: Eliminate the mismatched options. Any option that swaps a separation machine for a transport mechanism, or a processing operation for a plain physical property, breaks the category logic and can be discarded. Step 4: Confirm the final set. The pairing that keeps every item matched to its correct category throughout is (A) to (IV), (B) to (I), (C) to (II) and (D) to (III), which is option 1.
\[ \boxed{(A) - (IV), (B) - (I), (C) - (II), (D) - (III)} \]
