Option B, initial time-series file of temperature values, is also an example of raw data. Time-series data is data that is collected over time. The initial time-series file of temperature values contains the raw data that is used to create a time-series graph of temperature values.
Option C, a real-time GPS-encoded navigation file, is also an example of raw data. GPS-encoded navigation files contain the raw data that is used to track the location of a vehicle or person.
In conclusion, all of the options are examples of raw data.
