The correct answer is option 2, which states that statement 2 is correct, while statement 1 is incorrect.

Let`s analyze each option to understand why this is the correct answer:

Option 1: This option states that statement 1 is correct, while statement 2 is incorrect. However, this is not true. Carbohydrates are not the only source of energy to humans. While they are an important source of energy, our bodies can also utilize fats and proteins for energy production.

Option 2: This option states that statement 2 is correct, while statement 1 is incorrect. This is the correct answer. Fats do indeed provide more energy on oxidation compared to other foods. When fats are broken down in our bodies, they release a larger amount of energy compared to carbohydrates and proteins.

Option 3: This option states that both statements 1 and 2 are correct. However, as explained earlier, statement 1 is incorrect. Therefore, option 3 is not the correct answer.

Option 4: This option states that neither statement 1 nor statement 2 is correct. However, as explained earlier, statement 2 is correct. Therefore, option 4 is not the correct answer.

In conclusion, option 2 is the correct answer
