Correct answer: B

For country Y, the installed capacity values are 15, 18, 20, 20, and 24.

Annual growth rates:
2015-2016: ((18 - 15) / 15) x 100 = 20%
2016-2017: ((20 - 18) / 18) x 100 = 11.11%
2017-2018: ((20 - 20) / 20) x 100 = 0%
2018-2019: ((24 - 20) / 20) x 100 = 20%

Average annual growth = (20 + 11.11 + 0 + 20) / 4 = 12.7775%, which is approximately 12.77%. Therefore, option 2 is correct.
