ii and iii

The correct answer is D. II and III (II. You can't trust the accuracy of the information and III. The narrator may be lying or unable to give accurate information)

Explanation:

An unreliable narrator is a type of narrator that lacks credibility or who is not completely credible, this is usually related to a narrator being insane, being naive, lying, exaggerating or not being sure about certain events or what she or he is saying, which makes the reader unable to trust completely in what the narrator says, thinks or describes. Unreliable narrators are usually first-person narrators and are used by the author to reveal information that is hidden during the story or to make it more complex. In this way, as the narrator is not credible there is no accuracy of the information he gives ( statement II), as he might be lying or by any other reason providing information that differs from the reality presented in the story (statement III).

from the excerpt from the "the dark game" the reader can infer that folke cronholm was spying for the allied nations.
