All Options:

  • APrimary
  • BSecondary
  • CCensus
  • DOrdinal

Detailed Solution & Explanation

Let us define the types of data based on their source and collection:
1. **Primary Data**: Data collected by the investigator himself/herself for the first time for a specific investigation.
2. **Secondary Data**: Data that has already been collected by someone else or for another purpose, and is subsequently extracted, compiled, or analyzed for a new study.
3. **Application**: The investigator originally collected the salary data for 1000\displaystyle 1000 persons (which was primary data for that original collection). When the data for women is extracted from this existing dataset, the extracted data is being repurposed and is therefore classified as **Secondary data**.
Hence, **Option B** is the correct answer.
