Which of the following is a proper definition of engineering? a. I Engineering is the application of science and maths to solve problems. b. I Engineering [is] the application of science to the optimum conversion of the resources of nature to the uses of humankind. c. Engineering is about solving problems using the "best" solution for the "lowest" possible cost d. Engineering [deals with]complex systems structures, devices, and materials to fulfill functional requirements while also considering the limitations imposed by regulation, safety, cost and more.

The correct answer is b. Engineering [is] the application of science to the optimum conversion of the resources of nature to the uses of humankind.<br /><br />Engineering is a discipline that involves the application of scientific and mathematical principles to design, develop, and implement solutions to various problems. It encompasses a wide range of fields, including civil, mechanical, electrical, and chemical engineering, among others. The primary goal of engineering is to optimize the conversion of natural resources to meet human needs and improve the quality of life.<br /><br />Option a is partially correct but does not fully capture the essence of engineering. While engineering does involve the application of science and math to solve problems, it goes beyond that by considering the conversion of natural resources for human use.<br /><br />Option c is not a comprehensive definition of engineering. While cost-effectiveness is an important consideration in engineering, it is not the sole focus. Engineering also involves ensuring safety, functionality, and compliance with regulations.<br /><br />Option d provides a more detailed explanation of engineering, but it is not a proper definition. It describes some aspects of engineering, such as dealing with complex systems and considering various constraints, but it does not capture the overall goal of engineering, which is to optimize the conversion of natural resources for human use.
