Cinder cones are chiefly formed by:
A
Explosion
B
Strombolian Euroption
C
Both (a) and (b)
D
None of these
Explanation: 

Detailed explanation-1: -Cinder cones are chiefly formed by Strombolian eruptions. The cones usually grow up in groups and they often occur on the flanks of strato volcanoes and shield volcanoes . Cinder cones are built from lava fragments called cinders.

Detailed explanation-2: -Cinder cones They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.

Detailed explanation-3: -Strombolian eruptions are moderately explosive eruptions of basaltic magma with moderate gas content. Strombolian eruptions consist of intermittent, discrete explosive bursts which eject pyroclasts as high as hundreds of feet into the air in firework-like incandescent rooster-tails.
