उत्तर
A is true and R is false.
Explanation:
Block weathering commonly takes place in deserts due to high diurnal temperature range (large daily temperature variations) causing physical disintegration of rocks. The reason stating the daily range of temperature is low in deserts is incorrect, as deserts actually experience a high daily temperature range which causes block weathering.
