- Bluewater: The polluted water discharged to a freshwater resource directly through a pipe or indirectly through runoff or leaching from the soil, impervious surfaces, or other diffuse sources.
- Greywater: The water sourced from surface or groundwater resources and is either evaporated, incorporated into a product or taken from one body of water and returned to another

The correct pair in the given options is:
c) 1 only - Greenwater: The water from precipitation that is stored in the root zone of the soil and evaporated, transpired or incorporated by plants.
Explanation:
To understand the correct pair, let's delve into the definitions of each type of water footprint.
1. Greenwater:
Greenwater refers to the water from precipitation that is stored in the root zone of the soil and is either evaporated, transpired (released into the atmosphere through plant leaves), or incorporated by plants. It represents the water used by plants for their growth and sustenance. Greenwater is mainly derived from rainwater and plays a crucial role in supporting agriculture and natural ecosystems.
2. Bluewater:
Bluewater is the polluted water that is discharged directly to a freshwater resource through a pipe or indirectly through runoff or leaching from the soil, impervious surfaces, or other diffuse sources. It represents the water pollution caused by human activities such as industrial processes, sewage discharge, and agricultural runoff. Bluewater is characterized by its contamination and poses a threat to the quality of freshwater resources and ecosystems.
3. Greywater:
Greywater refers to the water sourced from surface or groundwater resources, which is either evaporated, incorporated into a product, or taken from one body of water and returned to another. It represents the water that is used for domestic purposes such as bathing, washing dishes, and laundry, excluding toilet water (blackwater) and highly contaminated water (brownwater). Greywater can be treated and reused for non-potable purposes such as irrigation and toilet flushing.
Therefore, from the given options, only option 1 correctly matches the definition of Greenwater. Greenwater is specifically related to precipitation stored in the root zone of the soil and utilized by plants. The definitions of Bluewater and Greywater do not align with options 2 and 3 respectively.
Hence, the correct answer is option 'C' - 1 only.
