Without seeing what the features are it is difficult to know the correct answer. Someone would need to know what the features are to know which is may interrupt a volcano.

composite
Galeras is a Strato/Composite volcano because of it's gently sloping sides.
COMPOSITE has more steeper sides then shield and folding
The textbook answer would be granitic or rhyolitic lava. In reality composite volcanoes are highly variable, erupting the full range from basaltic to rhyolitic (granitic) materal and everything in between includin andesite and dacite. One composite volcano in Africa erupts unique carbonatite lava.
Mount Mayon, the Phillipines, is a stratovolcano, or a composite volcano. The lava erupted has a high silica content and high viscosity, and is mainly andesitic. Mount Mayon is categorised as active, and is viewed as a 'perfect volcano' due to the symmetry of sides.

The sides of a volcano are known as flanks.
A composite volcano, also called a strato volcano, is built up from alternate layers of ash and lava. It has steep sides because when it erupts it lava is thick and viscous (andesitic) meaning that it does not travel great distances and stays on the side of the volcano. An example is Mount Vesuvius (which destroyed Pompeii).
Mt. St. Helens is considered a composite or Strato-Volcano due to the type of magma it erupts. The volcano is primarily composed of Andesite, a medium consistency magma. This medium viscosity magma makes it possible for both explosive and docile eruptions from the volcano. Although everyone remembers the May 18, 1980 explosive eruption, there is also much geologic evidence to support non-explosive lava extrusion type eruptions. However, due to the magma type that the volcano is primarily composed of, it is classified as a composite volcano with the typical steep sides, and potential for very explosive eruptions.
Krakatau is a stratovolcano. This type of volcano, also known as a composite volcano, is characterized by a tall, conical shape with very steep sides. The explosions are usually extremely violent.
A shield volcano is broad with gently sloping sides.
