Acollision between two pieces of continental crust at a converging boundary produces a
a. mid-ocean ridge.
b. deep-ocean trench.
c. rift valley.
d. mountain range.

The correct answer is - d. mountain range.

When two continental tectonic plates collide, they form a convergent tectonic boundary. Since both of the plates are on the same height, and have the same or very similar density of their crust, they push against each other, instead of one of the subducting bellow the other.

Because there's a very high pressure in the are where the two plates are pushing against each other, the land starts to lift up and gradually gains on elevation. As the land gains on height, over time a mountain range will be formed. A perfect example of this process are the Himalayan Mountains which are a result of the collision between the Indian and Eurasian tectonic plates.
