C. Economical . . . Climatic
D. Physical . . .Climatic

B: Physical & Economic

Explanation:

Physical water scarcity occurs when and where there is not enough water to meet both human demands and those of ecosystems to function effectively. Arid regions frequently suffer from physical water scarcity. It also occurs where water seems abundant but resources are over-committed.

Economic water scarcity is caused by a lack of investment in water infrastructure or insufficient human capacity to satisfy the demand of water in areas where the population cannot afford to use an adequate source of water.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
