The type of boundary represented by the two books is boundary
a. convergent
b. divergent
c. transform

i think the answer is convergent boundary

Convergent boundary: A convergent plate boundary happens when two plates move into one another and one plate slides beneath the other, in a process known as subduction.

Divergent boundary: A divergent boundary exists between two tectonic plates that are moving away from each other.

Transform boundary: A transform boundary is where plates slide sideways past each other.

So the answer would be convergent.
