Cells have multiple repair mechanisms to fix mutations in DNA, and and if the damaged DNA is duplicated, it causes mutation. Given these facts, cells have multiple repair mechanisms to fix what among the following options:
- a tree falling
 - direct damage to the lungs
 - that material's properties
 - damaged DNA duplication
 - an area swollen with pus
 - Veins and arteries.
 - the body's largest organ
 - The bending of a ray of light
