Marty said that ozone is located in atmosphere, and it is correct. The lithosphere is above the atmosphere, being the layer that first receives the sun rays, but the ozone is created and is a part of the atmosphere. Therefore, a) is incorrect.
Ozone is the only gas able to filter the ultraviolet radiation, and oxygen is necessary in cellular respiration, the process in which living things release energy from food. Therefore, Marty was right about those things and b) is also incorrect.
The ozone is composed of a molecule of oxygen (O2) + a free oxygen (O) = O3. So, Marty was correct, oxygen is O2 and ozone is O3. Therefore, c) is also wrong.
Marty said that oxygen is used in respiration, and that's correct. But, in order to be used in respiration, oxygen must become available via photosynthesis, the process in which carbon dioxide (CO2) is used to release O2. So, oxygen is produced by photosynthesis. Ozone is produced when the UV rays breaks a molecule of oxygen (O2) into two separate oxygen atoms. One of those atoms becomes united with another O2 molecule, creating Ozone (O3). Therefore, the ozone isn't produced by photosynthesis, like Marty said, and oxygen is. So, d) is the correct answer.
