How many copies did the Guardian sell in 2017?

The Guardian sold approximately 0.15 million copies in 2017, which reflects the ongoing trends in print media where many newspapers have experienced a decline in circulation due to the rise of digital news consumption. In this context, the figure represents a realistic figure in line with industry trends during that time, as many major publications had been struggling with maintaining their print sales due to changing reader habits and the increasing popularity of online news platforms. The other options provide higher figures that do not align with the actual reported sales, as they suggest a much more robust circulation that does not match the reality of the print market during that period.
