The correct answer is option 3: There was a stagnation in the spending on education as a percent of GDP. This means that the percentage of GDP allocated towards education remained relatively constant during the 2014-19 period.

Option 1 states that expenditure on education was 5% of GDP, which is not mentioned or supported in the question.

Option 2 states that expenditure on health was 4% of the social services expenditure. While this provides information about the health sector`s allocation within social services expenditure, it does not provide information about the overall social sector spending or the percentage of GDP allocated to health.

Option 4 states that health sector spending amounted to 10% of the total expenditure. However, the question specifically asks about social sector spending, not total expenditure.

Therefore, based on the information provided in the question, option 3 is the correct answer.
