Which state is commonly known as the "Spice Garden of India"?

The correct answer is Option (3) → Kerala

Kerala is called the “Spice Garden of India” because its warm, wet climate and the slopes of the Western Ghats suit spices such as black pepper, cardamom, ginger, turmeric, cinnamon, clove and nutmeg. Spices from the Malabar coast drew Arab, Chinese and European traders to its ports for centuries.
