The authors of the report urges online (A)/ platforms

Solution

The authors of the report urged online platforms and regulators to limit streaming resolution and set the default to SD to reduce per capita carbon emissions and combat climate change. A-The error lies in the usage of ‘urges’. To satisfy the subject-verb agreement rule, ‘urges’ should be replaced with either ‘urge’ or ‘urged’. C-Here also, the subject (online platforms and regulators) is plural, so, to satisfy the subject-verb agreement rule, ‘set’ should be used instead of ‘sets’. D- ‘To reducing’ should be replaced with ‘to reduce’ to signify the reason of the request made by the authors.
