The correct answer is: Only assumption I is implicit.
The statement “What a fool I am to rely on trickster like Shaleen!” expresses regret or disappointment that the speaker relied on Shaleen, who is a trickster. This suggests that the speaker believes that Shaleen is unreliable. However, the statement does not provide any evidence to support the conclusion that the speaker is a fool. Therefore, only assumption I is implicit.
Assumption I: Shaleen is unreliable.
This assumption is implicit in the statement because the speaker regrets relying on Shaleen. This suggests that the speaker believes that Shaleen is not a reliable person.
Assumption II: I am a fool.
This assumption is not implicit in the statement. The statement only expresses regret or disappointment that the speaker relied on Shaleen. It does not provide any evidence to support the conclusion that the speaker is a fool.
