*Remember, these are estimates and should fall within an acceptable range.

B. 10-20%


C. 70-85%

Answer 1

Answer:

Option B , 10-20%

Explanation:

Hence, option C cannot be correct.  

Now if we just look at the red colored coast line we could see that a considerable length of red coast can be seen which is any case is definitely more than 5%. Hence, the only option left is option B.
