Central Board Of Secondary Education [CBSE] — Wrong information in the question

Sir, myself raja singh of class x a . Recently i have given my english board exam and i was confuse to see the question of set 2/6/2 question no. 8 part (d). In this question there is written green meadows but you may check in ncert english book actually it is oxen meadows not green meadows beacause of this only i got confused and the timing was runnig out so i leave this question but this is not good as this is a board mistaken. So i request you to give marks to all the student who have appeared this question.
Thanks & regards
