Consider the following statements regarding mechanical weathering processes: 1. Frost wedging is most effective in equatorial regions where the temperature remains constantly high throughout the year. 2. Thermal expansion weathering (insolation weathering) is highly pronounced in hot deserts with high diurnal temperature ranges. 3. Exfoliation is a physical weathering process resulting from unloading or pressure release when overlying rocks are eroded. Which of the statements given above is/are correct?

Options:

• A: 2 and 3 only
• B: 1 and 2 only
