b). By using the Read PDF Text activity and providing the PDF file’s path.

Read PDF Text activity is the best method; here, the file will be obtained in text form and can be modified and updated as per demand.

c). By opening the PDF and using screen scraping to get its data.

The screen scraping tool can also be utilized to get data from a file, but this file will be in frames, and we can get image files from it. On these files, you can't do any formatting or editing of data. Data modification is not possible from this method.
