C. A new source of freshwater
Explanation:
The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater. 
In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.
- A new source of freshwater provides new resources for the ecosystem. 
- In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress. 
- Water is essential for life.
- Fresh water sources are incentives for choosing to live in a place or not. 
- A fresh water source increases the carrying capacity for humans in a certain region.

Smart home technology is the general term given to basic home amenities that have been fitted with communication technology, enabling some degree of either automation or remote control. It includes things like Home security systems. Environmental controls, like air conditioning, heating, and lighting.
Explanation:
Environmental controls, like air conditioning, heating, and lighting.A spectrometer is a device for measuring wavelengths of light over a wide range of the electromagnetic spectrum. It is widely used for spectroscopic analysis of sample materials. The incident light from the light source can be transmitted, absorbed or reflected through the sample The solution for space exploration is through using mass spectrometers which are used to identify miniature particles present in space. Mass spectrometers are also used in radioactive and carbon dating. When used with gas chronographs, mass spectrometers detect traces of toxic particles and contaminants in air.
