"It's a common belief that using cell phones can develop cancer due to harmful radiation. However, since the last decade, the number of cellphone users has increased eight-fold whereas deaths due to brain cancer have decreased by half. It can therefore be said that this belief is actually a myth"‐ CEO of a cell phone company. Which of the option weakens the statement.
1. According to many studies, occurrence of cancer also depends on the proximity of an individual to the source of radiations such as transmission towers
2. Cell phones emit radiations which are similar to those used for wireless satellite communications in remote areas
3. On introduction of microwave ovens about 15 years ago, similar facts had surfaced but microwave ovens survived the last of time
4. Research and technological intervention in cancer treatment over the past 12 years has decrease the number of fatalities by more than 70%
5. The study to correlate cellphone usage and cancer was conducted independently by government as well as non-government sources

Only option 4 weakens the given statement. The assumption made by the CEO is that radiation emitted is harmless and hence decrease in deaths due to cancer. Option 4 negates this by saying that development in the field of medical sciences has brought the rate of death down.
