Answers
the right response to the inquiry is (b) which is crater.
A volcanic pit is a generally roundabout misery in the ground brought about by volcanic activity.[1] It is commonly a bowl-molded element inside which happens a vent or vents.
Amid volcanic emissions, liquid magma and volcanic gases ascend from an underground magma load, through a cylinder molded course, until they achieve the cavity's vent, from where the gases escape into the environment and the magma is emitted as magma.
A volcanic cavity can be of substantial measurements, and once in a while of extraordinary profundity.
Amid particular kinds of unstable emissions, a fountain of liquid's magma chamber may exhaust enough for a territory above it to die down, shaping a sort of bigger misery known as a caldera.
