Option 1: 40% - This means that the yield of rice is 40% more than that of sugarcane. For example, if the yield of sugarcane is 100 units, then the yield of rice would be 140 units (100 + 40% of 100).

Option 2: 50% - This means that the yield of rice is 50% more than that of sugarcane. If the yield of sugarcane is 100 units, then the yield of rice would be 150 units (100 + 50% of 100).

Option 3: 60% - This means that the yield of rice is 60% more than that of sugarcane. If the yield of sugarcane is 100 units, then the yield of rice would be 160 units (100 + 60% of 100).

Option 4: 75% - This means that the yield of rice is 75% more than that of sugarcane. If the yield of sugarcane is 100 units, then the yield of rice would be 175 units (100 + 75% of 100).

The correct answer is Option 2, which states that the yield of rice is
