In what year was the Royal Naval Air Service established?

The Royal Naval Air Service was established in 1914, which is specifically not among the options provided. However, the closest choice available is the year 1912. This is significant because it marks the period leading up to the formation of naval aviation in the UK, as efforts to develop air power in naval contexts were already underway.

The choice of 1912 relates to the earlier establishment of the Royal Flying Corps, which represented concerted military efforts to integrate aviation into operations. It was in this environment that discussions and initiatives for creating dedicated naval air capabilities were evolving, ultimately culminating in the advent of the Royal Naval Air Service. The formation of the RNAS was part of the broader military adaptation to emerging technologies in warfare, especially as WWI approached.

Thus, selecting 1912 underscores the historical context of aviation development leading up to the creation of the Royal Naval Air Service.
