Final answer:
The exact number of Indigenous food types in AUSNUT is not determinable with the information provided; access to the updated AUSNUT database is necessary to provide an accurate answer.
Step-by-step explanation:
The question regarding the number of Indigenous food types found in AUSNUT cannot be answered accurately with the information provided. AUSNUT (Australian Food and Nutrient Database) is a comprehensive food composition database maintained by Food Standards Australia New Zealand. However, to determine the exact number of Indigenous food items listed in AUSNUT, one would need access to the most current version of the database. Without this data, it's not possible to select the correct option from A. 50, B. 100, C. 150, or D. 200.
Furthermore, the additional information provided, such as 'nones 401', 'norm 77', 'North Africa 223, 226', and 'North American Traditional Indigenous Food Systems (NATIFS) 22', does not offer relevant details that would help in identifying the number of Indigenous Australian foods listed in the AUSNUT database.
