The question is about identifying the correct adjective that describes a feeling of unease. The correct answer is B because 'uneasy' directly refers to a feeling of discomfort or unease. Option A is incorrect because 'comfortable' means the opposite of uneasy. Option C is incorrect because 'stable' refers to being steady or unchanging, which is not the same as uneasy. Option D is incorrect because 'secure' means to feel safe or protected, which is not the same as feeling uneasy.
