each question contain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below :
STATEMENT-1: ZSM-5 is a type of zeolites used as a catalyst in petrochemical industries.
STATEMENT-2: Zeolites are microporous aluminusilicates three dimensional network silicates in which some silicon atoms are replaced by aluminium atoms.

Options

A. if both the statement are TRUE and STATEMENT -2 is the correct explanation of STATEMENT - 1
B. If both the statement are TRUE and STATEMENT -2 is NOT the correct explanation of STATEMENT -1
C. If STATEMENT -1 is TRUE and STATEMENT is FALSE
D. If STATEMENT -1 is FALSE and STATEMENT -2 is TRUE

Answer

To analyze the given statements, we will break down the information provided in both Statement 1 and Statement 2.

### Step-by-step Solution:

1. **Understanding Statement 1**:
- **Statement 1**: "ZSM-5 is a type of zeolites used as a catalyst in petrochemical industries."
- ZSM-5 is indeed a type of zeolite, which is a microporous aluminosilicate. It is widely used as a catalyst in various chemical processes, particularly in the petrochemical industry for converting alcohols into hydrocarbons like gasoline.

2. **Understanding Statement 2**:
- **Statement 2**: "Zeolites are microporous aluminusilicates three-dimensional network silicates in which some silicon atoms are replaced by aluminium atoms."
- This statement accurately describes zeolites. They are indeed microporous materials composed of a three-dimensional framework of silicate and aluminosilicate structures, where some silicon atoms can be substituted by aluminum atoms, leading to the formation of a negatively charged framework that can accommodate cations.

3. **Evaluating the Truth of Each Statement**:
- Both statements are true.
- Statement 1 is true because ZSM-5 is used as a catalyst in the petrochemical industry.
- Statement 2 is true because it correctly describes the structure and composition of zeolites.

4. **Determining the Relationship Between the Statements**:
- While both statements are true, Statement 2 does not serve as an explanation for Statement 1. Statement 1 discusses the application of ZSM-5, while Statement 2 provides a general description of zeolites.

5. **Conclusion**:
- The correct answer is that both statements are true, but Statement 2 is not the correct explanation for Statement 1.

### Final Answer:
Both Statement 1 and Statement 2 are true, but Statement 2 is not the correct explanation of Statement 1.
