Option 1: Both the statements are individually true and Statement II is the correct explanation of Statement I.
This option suggests that both statements are true, and that Statement II explains the cause of skin cancer (Statement I). However, this is not accurate. While Statement I is indeed true, stating that skin cancer is generally caused by ultraviolet radiation, Statement II is false. The stratosphere actually acts as a protective layer that absorbs and filters out most of the harmful ultraviolet (UV) radiation from the sun, preventing it from reaching the Earth`s surface.
Option 2: Both the statements are individually true but Statement II is not the correct explanation of Statement I.
This option correctly acknowledges that both statements are true. However, it also correctly states that Statement II is not the correct explanation of Statement I. The stratosphere, as mentioned earlier, blocks a significant amount of ultraviolet radiation.
Option 3: Statement I is true but Statement II is false.
This option is the correct answer. It accurately states that Statement I is true, as skin cancer is indeed caused by ultraviolet radiation. However, it correctly identifies that Statement II is false, as the stratosphere does not allow the majority of ultraviolet radiation to enter the Earth from the sun.
