Functionally blind is best described as an educational description where the primary channel of learning is through tactile and auditory means.

• A. An educational description in which the primary channel of learning is through tactile and auditory means
• B. The same as legally blind with 20/200 vision
• C. A description of full reliance on visual input
• D. A classification based on eye anatomy

Answer: (A)

The main idea here is how functionally blind is described in education: it centers on how a learner accesses information, often using touch and hearing more than sight. The option that states learning occurs primarily through tactile and auditory means fits this focus exactly, capturing the instructional approach that suits someone who relies on non-visual senses. This describes how the learning process is adapted rather than prescribing a medical measurement. The other statements mix up concepts they don’t address: vision acuity figures like 20/200 pertain to medical vision criteria, not how learning happens; claiming full reliance on visual input contradicts the whole idea of using non-visual channels; and basing classification on eye anatomy misses the educational emphasis on how information is accessed and learned.
