The answer is B. In a destructive plate boundary, the descending plate, usually the oceanic plate begins to melt as it descends below into the mantle. This forms magma that rises and erupts onto the overlying continental plate through fissures. This volcanic activity is responsible for geographical features such as the volcanic island arc, which lies parallel to the subduction zone.

Option B is correct.

The type of landform that develops at plate boundaries where one oceanic plate descends beneath another is volcanic island arc.

Further Explanation:  

Volcanic island arc: It formed from the collusion or subduction of one tectonic plate under another in the ocean, and sometimes parallel to an oceanic trench

Justification for correct and incorrect answer:

a.

Rift valley: This option is incorrect.

It is lowland between mountain ranges or highlands created by the force of a fault or geologic rift.

b.

Volcanic island arc: This option is correct.

It formed from the collusion of one tectonic plate under another under the ocean, and sometimes parallel to an oceanic trench.

c.

Mountain formed by a batholith: This option is incorrect.

It is a large igneous rock that is formed beneath the surface of the Earth by the solidification and intrusion of magma.

d.

Lava plateau: This option is incorrect.

They are formed from liquid basaltic lava that is erupted from the number of successive volcanic eruptions through the number of vents.

Therefore, option B is correct.
