Which of the following is a type of volcano?

Cinder cone is indeed a recognized type of volcano. This type of volcano is characterized by steep sides and is built from particles and blobs of congealed lava ejected from a single vent. When volcanic material is expelled during an eruption, it falls back to the ground around the vent, forming a circular or oval cone shape. Cinder cones are typically the smallest type of volcano and can range from tens to hundreds of meters in height. They often erupt explosively and produce a variety of volcanic rocks known as cinders or scoria.

The other options do not accurately describe volcano types. "Dust cone" is not a recognized classification in volcanology, and it does not correspond to any established type of volcano. "Steep peak" refers more generally to a mountain feature rather than a specific volcano type. Similarly, "flatland volcano" does not conform to standard nomenclature in geology; while there are shield volcanoes, which create broad, low slopes, the term "flatland volcano" is not used in scientific literature to categorize volcanic forms. Therefore, cinder cone stands out as the correct answer in this context.
