Continental mantle plumes that are composed of felsic magma tend to be explosive when the Earth's surface is reached. These explosive eruptions create:

A. calderas

B. plutons

C. fissures

A. calderas

Explanation:

Calderas -

These are the huge cauldron shaped hollow, which is formed as soon as the magma chamber of any volcanic eruption gets released, which leads to the formation of a calderas.

As during a volcanic eruption, the magma chamber is released, and the surface gets collapsed, which leads to a huge gigantic depression, which leads to the formation of a calderas.

Hence, from the given information of the question,

The correct answer is A. calderas.

A. calderas

Explanation:

A caldera is a hollow form that is shortly formed after the melting of the magma chamber after eruptions and the above structure of the magma chamber is lost and the ground surface may partially or completely get collapsed and form a massive depression. This is triggered by the melting of the magma chamber under the volcanoes which are composed of the felsic magma and are explosive in nature. The eruption takes places in various stages and some exception includes the nonexplosive type of the shield volcanoes of Hawaii.
