In "the Deadliest Tsunami in History," warning for an approaching tsunami can be difficult because a. the large waves are very small when out at sea.
b. they are so common that the signs are often unnoticed.
c. they are more frequent now because of global warming.
d. the equipment designed to warn for them has not been released for public use.

I think the answer is A, but I am not sure. Please Help.
