Final answer:
Phillipe, 16, began his adolescent growth spurt and is likely to see this growth spurt end around the age of 18 since that's when growth in height typically ceases in males.
Step-by-step explanation:
The question involves predicting when Phillipe, who is 16 and just began his adolescent growth spurt, will likely see this growth spurt end. Based on data on puberty and growth in males, the peak height velocity in boys occurs around age 13.5 and growth in height generally ceases by about age 18. Therefore, the most accurate prediction for when Phillipe's growth spurt will end is around the age of 18 (Option C). This is because in boys, growth in height is typically complete once the long bones' ends ossify at the epiphyses which happens by about the age of 18.
