While researching a regional bird survey, a student has taken the following notes:

Over one winter, volunteers recorded bird sightings across the region using a phone app.
The app logged more than 90,000 sightings from about 3,000 volunteers.
Most of the volunteers lived in towns and cities and reported from nearby parks.
The region's remote forests and wetlands had almost no volunteers reporting from them.

The student wants to emphasize a limitation of the survey's data for describing the region's birds as a whole. Which choice most effectively uses relevant information from the notes to accomplish this goal?

AThe bird survey was a clear success, gathering more than 90,000 sightings from about 3,000 volunteers in a single winter. That level of public participation is one few regional studies of any kind ever manage, and it speaks to how eagerly ordinary people will pitch in when the science is made easy to join.

BAlthough the app logged more than 90,000 sightings, nearly all came from volunteers reporting in town and city parks, while the region's remote forests and wetlands were barely surveyed, so the data describe urban birds far better than the region as a whole.

CThe app logged more than 90,000 sightings from town and city parks, and the region's remote forests and wetlands had almost no volunteers reporting from them.

DThe bird survey had certain limitations that are worth keeping in mind when interpreting its results.
