Final answer:
The correct answer is option c. Sweden.
Step-by-step explanation:
In the Ingrian War, Russia fought against Sweden. This conflict took place from 1610 to 1617 and was part of the larger power struggles in Northern and Central Europe during that period. The Ingrian War was essentially a bid by Russia to regain access to the Baltic Sea and to reclaim territories lost during the Time of Troubles.
Despite Russia's efforts and eventual gains elsewhere over the centuries, such as expanding its empire and its presence in the Black Sea region under leaders like Peter the Great and Catherine the Great, the Ingrian War specifically saw Russia pitted directly against Sweden for control in the North.
