"A model for a prototype for a lighter breathing device for astronauts was created" is an example that describes a stage in the technological design process

Option A

Explanation:

In option 1, it clearly talks about designing a prototype. Since it involves technology, it can be categorized as a technological design process. The other three options are rather conducting studies on something. The final option can be categorized as scientific investigation, thus concluding option 1 as the suitable answer.

In general, to solve any issues, the knowledge skills gets changed to provide right physical solutions by the process is called technological design process. It involves various steps like scientific research such as emphasis, defining the issues, ideate, making a prototype and conducting test on it.
