Answer:
A. the Tsar's family was executed.
Step-by-step explanation:
On March 15, 1917, Russian political groups, led by liberal, bourgeois and socialist ideals and opposed to the local monarchical system, ousted Tsar Nicholas II. At that moment the Russian Revolution began and immediately the Tsar, his wife and all his children were executed in a barbaric and merciless manner. In that case, we can say that the immediate result of the March 1917 Revolution was that the Czar's family was murdered.
