Who was the first Filipino appointed as PC Chief in December 1917?

The correct answer identifies Brig. Gen. Rafael T. Crame as the first Filipino appointed as Chief of the Philippine Constabulary (PC) in December 1917. This appointment was significant in the context of the Philippine archipelago's transition from American colonial rule towards greater national self-determination. Crame's role represented a pivotal moment in Philippine history as it marked the increasing recognition and elevation of Filipino leadership in government institutions, particularly in law enforcement circles. The Philippine Constabulary was a key force in maintaining order during a time of change, and having a Filipino at its helm underscored the shift towards local governance and the eventual push for independence.

Other options mentioned do not align with this historical event. Taft and Henry T. Allen were prominent American figures during the early American administration of the Philippines, but they did not serve in that capacity within the Philippine Constabulary. Marcos, a later figure in Philippine politics, rose to prominence much later and was not involved in the establishment or early leadership of the PC.
