Refer to the different sources of water given below.
(i) Tube well `" "` (ii) River
(iii) Ocean `" "` (iv) Well
(v) Pond `" "`
Which of the following options shows the correct number of surface water sources (P) and groundwater sources (Q)?

Options

A. `{:(P,Q),(4,2):}`
B. `{:(P,Q),(3,3):}`
C. `{:(P,Q),(2,4):}`
D. `{:(P,Q),(1,5):}`

Explanation

To solve the question regarding the classification of water sources into surface water sources (P) and groundwater sources (Q), we need to identify each source of water listed:

1. **Tube well**: This is a groundwater source because it taps into underground water.
2. **River**: This is a surface water source as it is found above the ground.
3. **Ocean**: This is also a surface water source since it is a large body of water found on the Earth's surface.
4. **Well**: This is a groundwater source as it accesses water from underground.
5. **Pond**: This is a surface water source because it is a small body of still water on the surface.

Now, let's categorize them:

- **Surface Water Sources (P)**:
- River
- Ocean
- Pond

Total Surface Water Sources (P) = 3

- **Groundwater Sources (Q)**:
- Tube well
- Well

Total Groundwater Sources (Q) = 2

Now, we can summarize our findings:
- P (Surface Water Sources) = 3
- Q (Groundwater Sources) = 2

Thus, the correct option showing the number of surface water sources (P) and groundwater sources (Q) is **P = 3 and Q = 2**.
