Answer 2

d. rocks is not evidence of star formation.

• The rock formation is associated with the processes like lithification, erosion, precipitation, weathering etc.
• On the other hand, star formation is associated with star-forming regions, also known by the name, stellar nurseries.
• The thermal energy for star formation is obtained by the fusion of hydrogen and helium.
• Infrared radiation can penetrate through the dust surrounding the star formation. Thus, it provides evidence to astronomers.
