Answer:
D. Then Robin grew angry, for no stripling likes to be taunted with his green years.
Step-by-step explanation:
This is the statement that best explains why Robin has a conflict with the foresters. In this line, first of all, we learn that Robin is angry, which signals a conflict. We learn that Robin is angry because he is "taunted" with "his green years." To taunt means to mock or to make fun of. Moreover, his "green years" refers to Robin's young age. Robin is most likely angry about the fact that the foresters made fun of his age, which leads to conflict.
