Common cold is a respiratory disorder mainly caused due to viruses. It is also called as acute coryza. It is mainly caused by coronaviruses and rhinoviruses.
Cancer is the disease of abnormal, uncontrollable cell growth leading to the formation of tumors. This disease can by genetical or can be caused by mutagenic agents (physical/chemical), radiations, over exposure to sunlight.

  1. Brain damage

  2. Lung cancer

  3. DNA damage

  4. All of the above

Show answer
Correct Option: D
Explanation:

Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling or disposal are also considered e-waste. E-waste recycling spews dioxins into the air. E-waste recycling using uncontrolled processes is a major source of dioxin-related compounds. Air around e-waste recycling areas in Guiyu, China, contains the highest levels of dioxins ever recorded. When computers, televisions, music systems, and other electronic products reach the ends of their lives, they often end up in China or other developing countries as e-waste. Such waste is a serious environmental threat in these parts of the world because of the poorly regulated conditions under which the waste is dismantled. E-waste affects brain, lungs and all over the body. There is also evidence of cell membrane lesion, cause DNA single-strand breaks. DNA breaks can increase the likelihood of developing cancer. DNA damages are a special problem in non-dividing or slowly dividing cells, where unrepaired damages will tend to accumulate over time. On the other hand, in rapidly dividing cells, unrepaired DNA damages that do not kill the cell by blocking replication will tend to cause replication errors and thus mutation.
