In "the deadliest tsunami in history", all of the following were effects of the tsunami except
(a) lack of food
(b) no clean water
(c) mass animal deaths
(d) the coastline was destroyed

So I think the most logical answer is Actually D. because there was mass animals deaths and no clean water for a fact. The polluted water would make the animals bodies too dirty to eat and would make people sick, therefore it also makes sense that there was a lack of food and that leaves only D.

≈ 31.8309=

take the square root of each side to find r

=r

r ≈5.641
