A recent Atlantic exploration found four vacuum tubes in the middle of the ocean. These vacuum tubes were similar to those used in industrial and commercial radios. Given the lack of supporting evidence, historians turned to radiology dating, which estimated that these vacuum tubes belong to the 1910s. Based on this evidence, historians claim that these vacuum tubes belonged to a plane involved in the war in the 1910s.
Which of the following, if true, would provide the most support to the historians' argument?
A) The kind of vacuum tubes discovered in the exploration have never been used in planes between 1914 and 1926.
B) Planes in the 1910s had the provision to carry more than three vacuum tubes.
C) 10 years ago, the Blackbox of a plane belonging to the 1910s was also found in the Atlantic Ocean.
D) There is documented evidence that several planes crashed over the Atlantic during the Great War.
E) The Great War involving numerous nations and an extraordinary number of fighter planes has occurred during the 1910s.
