Consider the following three methods of collecting data
(1) collecting data from government offices
(2) collecting data from public libraries
(3) collecting data by telephonic interview
Select the correct answer using the code given below

Options

A. All the three methods give data
B. 1 and 2 give secondary and 3 gives primary data
C. 1 and 3 give secondary and 2 gives primary data
D. 2 and 3 give secondary and 1 gives primary data

Explanation

To solve the question about the methods of collecting data, we need to analyze each method and determine whether the data collected is primary or secondary.

### Step-by-Step Solution:

1. **Understanding Data Types**:
- **Primary Data**: This is data collected firsthand for a specific research purpose. It is original and collected directly from the source.
- **Secondary Data**: This is data that has already been collected by someone else for a different purpose. It is not original and is obtained from existing sources.

2. **Analyzing Method 1: Collecting Data from Government Offices**:
- Data collected from government offices typically consists of records, reports, and statistics that have already been compiled. Therefore, this method yields **secondary data**.

3. **Analyzing Method 2: Collecting Data from Public Libraries**:
- Public libraries house a variety of documents, books, and reports that have been published by other entities. The data obtained from libraries is also previously collected and published, making it **secondary data**.

4. **Analyzing Method 3: Collecting Data by Telephonic Interview**:
- Conducting telephonic interviews involves directly asking questions to respondents and collecting their responses in real-time. This method provides **primary data** as it is original and collected directly from the source.

5. **Conclusion**:
- From the analysis:
- Method 1 (Government Offices) = Secondary Data
- Method 2 (Public Libraries) = Secondary Data
- Method 3 (Telephonic Interview) = Primary Data
- Therefore, the correct classification is:
- 1 and 2 yield secondary data.
- 3 yields primary data.

### Final Answer:
Based on the analysis, the correct answer is **Option B** (1 and 2 are secondary data, and 3 is primary data).
