80% = 704 papers

1% = 8.8

100% = 880

So total number of papers published were = 880

Out of these 880, 80% (704) were affected.

In 2016

Increase in number of papers = 10% of 880 = 88

Total number of papers published = 880 + 88 = 968

Increase in number of pages with errors = 20% of 704 = 140.8

Total number of pages with errors = 704 + 140.8 = 844.8

In 2017

Increase in number of papers = 10% of 968 = 96.8

Total number of papers published = 968 + 96.8 = 1064.8

Increase in number of pages with errors = 20% of 844.8 = 168.96 ≈ 169

Total number of pages with errors = 844.8 + 169 = 1013.8

In 2018

Increase in number of papers = 10% of 1064.8 = 106.48

Total number of papers published = 1064.8 + 106.48 = 1171.28

Increase in number of pages with errors = 20% of 1013.8 = 202.76

Total number of pages with errors = 1013.8 + 202.76 = 1216.56

The number of pages with errors exceeds the total number of pages published in 2018. So C is the answer.
