To determine the correct type of thermometer for each temperature range, we need to understand the operational range and application of different types of thermometers.

Step 1: Analyze the temperature ranges for the thermometers listed in Column-I.
- **(i) – 60°C to 140°C**: This is suitable for common usages such as in laboratories or kitchens. A Mercury thermometer can be used here as it is effective within this range but is limited by its upper range (usually around 350°C). A Thermoelectric thermometer could also work due to its operation with thermocouples but generally for limited ranges.

Step 2: Next temperature range is (ii) – 260°C to 1200°C: This range is suitable for a Thermoelectric thermometer or Radiation thermometer (also known as infrared thermometer) which could measure high-temperature ranges depending on the material being measured.

Step 3: For (iii) – 200°C to 1600°C: This range is best suited for a Platinum thermometer as it's made for high-temperature applications and is used in various scientific measurements. Mercury thermometers are not suitable here due to their maximum working range.

Step 4: Finally, for (iv) – 4000°C to 5000°C: This extremely high range typically necessitates special thermometers like Platinum resistance thermometers (which can measure a very large range up to this temperature) or other advanced devices.

Conclusion: Based on the analysis:
- (i) matches with [C] Mercury thermometer,
- (ii) matches with [B] Thermoelectric thermometer,
- (iii) matches with [D] Platinum thermometer,
- (iv) matches with [A] Radiation thermometer.

Thus, the correct associations for Column-I and Column-II lead us to conclude that the types of thermometers can be correctly identified as such.
