B. satellite photographs.
Explanation:
Technology can be defined as a branch of knowledge which typically involves the process of applying, creating and managing practical or scientific knowledge to solve problems and improve human life. Technologies are applied to many fields in the world such as medicine, information technology, cybersecurity, engineering, environmental etc.
Basically, knowing how to use a technology simply means a scientist understands the appropriate method or technique to be used in the application of a technology such as when solving a problem. Also, knowing when to use a technology means to know the appropriate time to use a particular technology without it having any repercussion or adverse effect.
Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances.
In order to determine the presence and concentration of water pollutants, scientists are most likely to use the following techniques;
I. Chemical analysis of water samples.
II. Analysis of indicator species.
III. Genetically engineered bacteria and yeasts.
IV. Chemical analysis of sediment.
However, satellite photographs are likely to be used to get a graphical illustration of the physical environment.
