What will happen where two continental plates collide at a convergent boundary?

One plate is subducted beneath the other.

The direction shifts and it becomes a transform boundary.

The plates push up, forming a mountain range.

A volcanic island arc is formed.

the plates push up, forming a mountain range

Explanation:

When continental plates collide, mountains form. The least understood of all tectonic boundaries, continental plates have greater density, sometimes reaching lower than the mantel.

Option (3)

Explanation:

The collision of two continental plates results in the sandwich pattern, in which the plates pushes one another in the upward direction, giving rise to the formation of huge mountain ranges. The rocks are highly folded and faulted here due to the immense compressional force. This type of plate motion results in the earthquakes of various magnitude. One of the famous example of this type of convergent plate boundary (continental-continental) is the Himalaya that formed due to the collision between the Eurasian plate and the Indo-Australian plate.

Thus, the correct answer is option (3).
