Answer:
B- the usual South America-to-Southeast Asia winds ease.
Explanation:
The usual South America-to-Southeast Asia winds did not blow from west to east because of El Nino event. In normal condition, the winds blow easterly from South America-to-Southeast Asia which means from west to the east direction but due to El Nino event, the wind blows is reversed which causes the blowing of winds towards westerlies which means from east to the west direction so the usual blowing of winds from South America-to-Southeast Asia did not occur.
