Final answer:
The term 'capo de squadra' evolved into the modern military rank of Captain, which is the head of a company or unit. Option D.
Step-by-step explanation:
The modern military rank that originated as capo de squadra is Captain. The term 'capo de squadra' was used in the Italian language, and it translates to 'head of a squad'.
Over time, this evolved into the role of a Captain, who is typically in charge of a company or a similar-sized unit within the military, depending on the specific branch of armed forces.
During the 16th century, in Italy, the capo de squadra was a rank given to a soldier in charge of a squad or a small group of soldiers.
Over time, this rank evolved and spread to other militaries, including the modern military, where it became known as Captain.
Examples of historical figures who held the rank of Captain include General George Washington (a) and Major Benedict Arnold (c).
Hence, the right answer is option D.
