Read the given paragraph.
Process P helps in drying up of our wet clothes when hung on clothesline under sunlight. Process Q makes the mirror in our washroom foggy when we take hot shower. Process R is responsible for loss of water present in soil through leaves of plants.
Identify the processes and select the correct option regarding them.

Options

A. All the processes P. Q and R involve the change of state of matter.
B. Process P decelerates with increase in temperature whereas processes Q and R speed up with increase in temperature
C. In absence of process Q water present in atmosphere will not precipitate or fall down on Earth's surface.
D. Both A and C

Explanation

To solve the question, we need to identify the processes P, Q, and R described in the paragraph and then select the correct option regarding them.

### Step-by-Step Solution:

1. **Identify Process P**:
- The paragraph states that Process P helps in drying wet clothes when hung on a clothesline under sunlight.
- The drying of clothes occurs due to the conversion of water from liquid to vapor when heat is applied.
- **Conclusion**: Process P is **Evaporation**.

2. **Identify Process Q**:
- The paragraph mentions that Process Q makes the mirror in the washroom foggy when taking a hot shower.
- This fogging occurs because water vapor from the hot shower cools down on the cooler surface of the mirror, turning back into liquid water.
- **Conclusion**: Process Q is **Condensation**.

3. **Identify Process R**:
- The paragraph describes Process R as responsible for the loss of water present in soil through the leaves of plants.
- This process involves water vapor being released from the leaves into the atmosphere.
- **Conclusion**: Process R is **Transpiration**.

4. **Select the Correct Option**:
- Now that we have identified the processes:
- P = Evaporation
- Q = Condensation
- R = Transpiration
- We need to evaluate the statements regarding these processes:
- **Statement 1**: P, Q, and R are involved in changes in the state of matter.
- **Statement 2**: P decreases with an increase in temperature (this is incorrect; evaporation increases with temperature).
- **Statement 3**: Q and R speed up with an increase in temperature (this is misleading; while transpiration can increase with temperature, condensation does not speed up with temperature).
- **Statement 4**: In the absence of process Q, water present in the atmosphere will not precipitate (this is true; condensation is necessary for precipitation).
- Therefore, the correct option is that both statements A and C are correct.

### Final Answer:
The correct option regarding the processes P, Q, and R is that both A and C are correct.
