In this question, we are given List I and List II. List I consists of the names of different grasslands such as Pampas, Veld, Downs, and Llanos. List II consists of the corresponding countries where these grasslands are located.

To solve the question, we need to match the grassland names with their respective countries. Let`s analyze each option:

Option 1: The grassland Pampas is correctly matched with Argentina, Veld is correctly matched with South Africa, Downs is correctly matched with Australia, and Llanos is correctly matched with Venezuela. Therefore, option 1 is the correct answer.

Option 2: The grassland Pampas is correctly matched with Argentina, but Veld is incorrectly matched with Australia (it should be South Africa), Downs is incorrectly matched with South Africa (it should be Australia), and Llanos is correctly matched with Venezuela. Therefore, option 2 is not the correct answer.

Option 3: The grassland Pampas is correctly matched with Venezuela (it should be Argentina), Veld is correctly matched with South Africa, Downs is incorrectly matched with South Africa (it should be Australia), and Llanos is correctly matched with Argentina (it should be Venezuela). Therefore, option
