The correct answer is letter D

The Vikings were a people of Nordic European origin who were characterized by their great ability to navigate on the high seas and by the actions of conquest and looting of various parts of Europe during the Middle Ages. Vikings were originally from Scandinavia, that is, from the region that today comprises Norway, Sweden and Denmark, but ended up expanding to Iceland, Normandy, Great Britain, Eastern Europe and the Iberian Peninsula. Some authors believe it is possible to speak of a Viking Age, which would have lasted from AD 793 to AD 1066.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
