What type of plate boundary could form a mountain chain of sedimentary rock A. Convergent boundary could form a mountain chain of sedimentary rock
B .Divergent boundary between two oceanic crusts
C. Divergent boundary of oceanic crust and continental crust
D. Convergent boundary of oceanic crust and continental crust

A. Convergent boundary could form a mountain chain of sedimentary rock

Explanation:

The type of plate boundary that could form a mountain chain of sedimentary rock is a convergent boundary.

Such convergence often takes place between two continental crusts that collides with one another. By so doing, shortening occurs and their is an uplift. The sedimentary beds are raised up to towering peaks in this kind of convergence. For oceanic - continental crust convergence, subduction will not allow for the mountain chain to form. Also, this is the same case with oceanic - oceanic crust convergence.

Yes that is correct answer in 6
