Correct Answer: B

Rationale: The correct answer is B: Ulnar nerve. The "funny bone" is a term used to describe the ulnar nerve that runs along the inside of the elbow. When this nerve is bumped, it can cause a tingling or funny sensation. The ulnar nerve is not a bone, ruling out choices A and C. Choice D, biceps brachii, is a muscle in the arm and is not related to the "funny bone" sensation.

Correct Answer: D

This aligns with the definition of 'tremulous' meaning quivering and weak. Choice A is incorrect as it describes a different physical characteristic. Choice B is incorrect as it focuses on color and vitality rather than the intended meaning of the word. Choice C is incorrect as it describes a different type of hand movement unrelated to the context of the sentence.
