Answer:
A. He grew close to Alexandra, who gave him considerable political power.
Step-by-step explanation:
Rasputin was well known for his "healing" abilities. The Romanovs' son Alexei had hemophilia, which meant he could bleed out. Rasputin supposedly saved the boy, and the Romanovs kept him in the palace. When the Tsar went to war, Alexandra was left in charge, so she got help from Grigori. Many believe that they had a romantic relationship, but no evidence has ever been found. Alexandra gave Rasputin political power to help her run the country while her husband was away.
