The correct answer is indeed the reflex hammer. This instrument is specifically designed to test deep tendon reflexes by delivering a small, controlled strike to a tendon, which prompts a reflex response from the associated muscle. Reflex hammers are commonly used in clinical settings to assess the functioning of the nervous system and can help identify any abnormalities in reflex pathways.

In contrast, an otoscope is used for examining the ears, which does not assess reflexes. An ophthalmoscope is utilized for examining the eyes, providing a view of the retina and other internal structures, rather than reflex responses. An electrocardiogram, on the other hand, records the electrical activity of the heart, unrelated to testing reflexes. Thus, the reflex hammer stands out clearly as the appropriate tool for evaluating reflex responses in the body.
