Given below are two statements:
Statement I: In froth floatation method a rotating paddie againstates the mixture to drive air out of it.
Statement III: Ion pytrizes are generally avoided for extraction of iron due to environmental reasons.
In the light of the above statement,choose the correct answer from the options given below:

Options

A. Both Statement I and statement II are false
B. Both Statement I and statement II are true
C. Statement I is false but statement II is true
D. Statement I is true but statement II is false.

Answer

To solve the question, we need to analyze both statements provided:

### Step 1: Analyze Statement I
**Statement I**: "In froth flotation method, a rotating paddle agitates the mixture to drive air out of it."

- **Explanation**: The froth flotation method is a process used for separating hydrophobic materials from hydrophilic ones. In this method, a rotating paddle is used to agitate the mixture, which actually helps in introducing air bubbles into the mixture rather than driving air out. The air bubbles attach to the hydrophobic particles and rise to the surface, forming a froth that can be removed. Therefore, this statement is **false**.

### Step 2: Analyze Statement II
**Statement II**: "Iron pyrites are generally avoided for extraction of iron due to environmental reasons."

- **Explanation**: Iron pyrites (FeS2), also known as fool's gold, can produce sulfur dioxide when burned, which is a pollutant and can lead to acid rain. Due to these environmental concerns, the use of iron pyrites for the extraction of iron is generally avoided. Thus, this statement is **true**.

### Conclusion
- **Statement I** is false.
- **Statement II** is true.

### Final Answer
Since Statement I is false and Statement II is true, the correct answer is that only Statement II is correct.
