Which of the following would be the most appropriate gift for the first birthday of an infant who is blind?

The most appropriate gift for an infant who is blind would be one that makes a musical chime with a soft tap. This option engages the child's senses beyond just sight, providing auditory stimulation that can help in sensory development. Infants who are blind rely heavily on their other senses, and a toy that produces sound can encourage exploration and play. The musical chime can also attract the child's attention, allowing them to connect with the toy, promoting both cognitive development and fine motor skills as they learn to reach for and tap it to create sound.

In contrast, a brightly colored toy with no sound offers no sensory engagement for a child who cannot see. Such a toy would not be effective in stimulating the child's interest or development. A book with large print images would also be unsuitable, as the infant would not benefit from the visual aspect of the book without the ability to see. Lastly, while a simple rattling toy does produce a sound, it may not provide the same level of auditory engagement and enrichment as a toy with musical elements. Therefore, the musical chime is the most appropriate and beneficial choice for an infant who is blind.
