Answer:
A secondary pollutant
Explanation:
Pollutants can broadly be classified into two main categories based on their formation or synthesis. 1: Primary pollutants, 2: Secondary pollutants.
1: Primary pollutants
Primary pollutant can be considered as any environmental pollutant that is being directly emitted from a certain source like when we burn coal carbon di oxide is directly emitted into the atmosphere so CO2 is a primary pollutant.
Similarly sulfur di oxide or SO2 is also a primary pollutant that is emitted by the gas emissions of motor vehicles.
2: Secondary pollutants:
On the other hand, secondary pollutant is something that is not directly emitted on earth as an environmental pollutant but some how it is formed due to a reaction of primary pollutant.
Such as mentioned in the question that SO2 when oxidized in air in the presence of enzymes and water, it form H2SO4 or acid rain which directly falls on earth and incurs great amount of damage to not only living organisms but also non-living organisms such as marble buildings.
Therefore, acid rain is secondary pollutant. Please see picture for better understanding.

Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.

Explanation:
This rapid population growth has an adverse effect on the natural resources and quality of life.
However, overpopulation has a deleterious effect on the environment due to the current lifestyle.
There would be rampant exploitation of natural resources, excess human waste accumulation, chances of epidemics, etc.
Besides, it would also lead to socio-economic problems like poverty, malnutrition, violence, corruption, etc.
Human overpopulation occurs if the number of people in a group exceeds the carrying capacity of the region occupied by that group.
