Correct Answer : Option a

Explanation
Statement 1 is correct: Albedo is the measure of the reflectivity of a surface, expressed as a percentage of incoming radiation reflected. Objects with higher albedo, such as ice or snow, reflect more light, appearing brighter to observers.

Statement 2 is correct: Tundra regions are often covered with snow or ice, which can reflect up to 80% of incoming solar radiation. In contrast, tropical evergreen forests have dense, dark vegetation with much lower albedo absorbing more sunlight.

Statement 3 is not correct: Land surfaces, particularly deserts and ice-covered regions, tend to have higher albedo than oceans and water bodies. Water absorbs most of the incoming solar radiation due to its high specific heat capacity.
