sorry i feel a little bit confuse, refer to the note for Internal & external sources data, said that Internal data are data collected from our own records. These are the main source of primary data. External data are data collected from elesewhere – e.g. the internet, government statistics, financial newspaper. These will be secondary data. Refer to this note so i choose answer is D, coz in my mind for our own record is primary data, for information from elesewhere is secondary data.
Is i misunderstood the meaning?
