Final answer:
The wife of the first False Dmitry was Maryna Mnishek, a Polish noblewoman. She was pivotal in his quest for the Russian throne during the Time of Troubles by securing alliances through their marriage. The other named individuals were not associated with Dmitriy or his reign.
Step-by-step explanation:
The wife of the first False Dmitry was Maryna Mnishek. The first False Dmitry, also known as Dmitry Ivanovich or Pseudo-Demetrius I, was a pretender to the Russian throne during the Time of Troubles, a period of political crisis in the early 17th century. Maryna Mnishek was a Polish noblewoman whom the false tsar married to gain support from Polish nobility and the Catholic Church in his quest for power. This marriage also had political implications, as it was meant to secure an alliance with certain Polish factions during his attempt to claim the Russian throne.
The other options provided, such as the wife of Boris Godunov, Anastasia Romanova, and Elena Glinskaya, were related to different historical figures and not associated with the first False Dmitry's life.
