Which statement about the capability of an O-type star to trigger the formation of other stars is NOT correct?
A) O-type stars are massive. When they form stellar nebulae, as the Sun did, small stars form instead of planets.
B) The H II region surrounding an O-type star expands into the giant molecular cloud, producing a shock wave that can compress the un-ionized material and cause it to collapse.
C) O-type stars are massive and thus have short lifetimes. After an O-type star erupts in a supernova, the material it ejects into space can eventually condense to form a new generation of stars.
D) The shock wave produced when an O-type star forms a supernova can compress the ISM and cause it to collapse.
