Show answer & explanation
Correct answer: C
Nigeria values from the table are:
2015 = 11.6, 2016 = 10.5, 2017 = 13.2, 2018 = 15.9, 2019 = 14.2 million tonnes.
Percentage change over the previous year:
2016: ((10.5 - 11.6) / 11.6) × 100 = -9.48%
2017: ((13.2 - 10.5) / 10.5) × 100 = 25.71%
2018: ((15.9 - 13.2) / 13.2) × 100 = 20.45%
2019: ((14.2 - 15.9) / 15.9) × 100 = -10.69%
The maximum percentage increase/decrease by magnitude is 25.71%, which occurs in 2017.
Hence, the correct answer is 2017.
