The presence of ozone (O3) in the atmosphere of Earth has several effects:

a. Hinders higher rate of photosynthesis: This statement is not entirely accurate. Ozone at ground level can be harmful to plants and can hinder photosynthesis, but ozone in the stratosphere (where the ozone layer is) does not directly affect photosynthesis.

b. Helps in checking the penetration of ultraviolet rays on Earth: This is true. The ozone layer in the stratosphere absorbs most of the Sun's harmful ultraviolet (UV) radiation. If this layer were to deplete, more UV rays would reach the Earth's surface, causing skin cancer and cataracts in humans and harm to the environment.

c. Has been responsible for increasing the average global temperature in recent years: This is not true. Ozone in the lower atmosphere (troposphere) is a greenhouse gas and can contribute to warming. However, the main drivers of recent global warming are carbon dioxide and other greenhouse gases.

d. It is advantageous since it supplies O2 for people traveling on jets: This is not true. The oxygen that we breathe at ground level is O2, not O3. Ozone is actually harmful to breathe. Even at high altitudes, where jets fly, the air is primarily composed of regular oxygen, not ozone.
