Correct answer: A

Solar: 15%. Wind: 12%. Both are shares of the same total, so compare the percentages directly.
$15 : 12$ ; divide both by 3 to get $5 : 4$ .

Worth noting

$4 : 5$ is wind to solar, the ratio reversed. $3 : 4$ is solar to hydro $(15 : 20)$ . $5 : 9$ compares solar with solar and wind together.
