As the two plates collide,the denserr oceanic plate will subduct under the less dense continential plate, causing the continential plate to arch up and form a mountain range.
Let's look into it one by one:
A. An underwater mountain range will will run along the boundary on the oceanic plate. - This is false.
As the oceanic plate subducts under the continential plate, there is no chance for the denser material to accumulate while subducting. What would be find instead is ocean trench.
B. A mountain range will form in the middle of the continental plate. - This is false.
Although pressure will be applied and there would be stress accumulating on the continential plate, the middle is very unlikely to be affected.
C. A mountain range will run along the boundary on the continental plate. - This is true.
As the subduction happens, the continential plate will accumulate as it is less dense. The rock would fold up to form mountain ranges. For example, Rockies is one off the mountain range along the plate.
D. A chain of islands will form along the boundary of the oceanic plate. - This is false.
Similarly to A. it is not possible for the plate to accumulate when it slides under the other plate.
Therefore the answer is C. A mountain range will run along the boundary on the continental plate.

Answer:
Smallpox has had a major impact on world history, not least because indigenous populations of regions where smallpox was non-native, such as the Americas and Australia, were rapidly decimated and weakened by smallpox. During the 18th century the disease killed an estimated 400,000 Europeans each year, including five reigning monarchs, and was responsible for a third of all blindness. After successful vaccination campaigns throughout the 19th and 20th centuries, the WHO certified the global eradication of smallpox in December 1979. Smallpox is one of two infectious diseases to have been eradicated.
