According to government figures, the rate of people treated

Option A - INCORRECT.
Looking at the time frame of when the disease have been in existence 1980 till date and yet an absolute cure has not been detected, then the increase in the rate of people treated for melanoma did not result from an improved ability to detect the disease at a treatable stage of development.

Option B - CORRECT.
This option best describes the stand with which the argument depends on. Rating the statistics of the increase rate of this disease since 1980 and the poor chances of people surviving it is very low due to efforts made to hart the destruction of the ozone layer which serves to filter out the cancer causing the ultraviolet rays of the sun, have been unsuccessful. Therefore. the chances that an individual who contracts melanoma will survive is uncertain till date except if tomorrow researchers will discover a cure for this long time disease.

Option C - INCORRECT.
Due to improvements in medical technology, melanoma patients are more likely to live longer after detection of the disease than they were in 1980, but its dishearten to know that till date researchers have been unable to halt the destruction of the ozone layer, which serves to filter out the cancer-causing ultraviolet rays of the sun, have been largely unsuccessful.

Option D - INCORRECT.
Maybe, It is highly unlikely that medical researchers will discover a cure for melanoma at any time in the foreseeable future but the certainty is low due to new inventions in the medical sector and researchers are still working hard to find a cure for it each day.

Option E - INCORRECT.
It is certain that, the rate of melanoma will continue to increase unless the government poses a ban on the use of chlorofluorocarbons, which are largely responsible for the destruction of the ozone layer. However, researchers are working effortlessly to curb the exclamation of the deadly form of cancer disease.
