The correct answer is: C. Fundamental research.
Fundamental research is a type of research that is conducted to gain a better understanding of the natural world. It is often theoretical in nature and does not have a specific application in mind. Newton’s laws of motion are an example of fundamental research, as they were developed to explain the basic principles of motion.
Descriptive research is a type of research that is conducted to describe a particular phenomenon. It is often used to gather information about the prevalence of a certain condition or behavior. Descriptive research can be used to generate hypotheses about the causes of a phenomenon, but it cannot be used to test those hypotheses.
Sample survey is a type of research that is conducted to collect data from a sample of a population. The data collected from the sample is then used to make inferences about the population as a whole. Sample surveys can be used to gather information about a wide range of topics, such as public opinion, consumer behavior, and health status.
Applied research is a type of research that is conducted to solve a specific problem. It is often practical in nature and has a specific application in mind. Applied research can be used to develop new products, improve existing products, or find new ways to solve problems.
In conclusion, Newton’s laws of motion are an example of fundamental research, as they were developed to explain the basic principles of motion.
