Which would be the best source for researching information about different types of crabs?
a) a zoology textbook
b) a book titled, crabs a-z
c) an encyclopedia entry about lobsters
d) a newspaper article about hermit crabs as pets

A part of me wants to say A just because a textbook is a highly credible source, but i think the answer is B because a book PURELY about crabs would have a lot more information about different types than a general zoology textbook. C & D are mostly irrelevant bc C isn't the right animal and D is too specific

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
