Answer :
Final answer:
Students with visual impairment and blindness may experience challenges in learning, may require alternative methods to access materials, and do not inherently have a keen sense of hearing or a preference for bright colors. Therefore the correct answer is a) They have keen sense of hearing.
Explanation:
The general characteristics of students with visual impairment and blindness vary but there are common experiences that can impact their learning. Contrary to the notion that they may have a keen sense of hearing, not all visually impaired individuals have enhanced other senses. It's also a misconception that they would excel in visual arts or prefer bright and vibrant colors.
In reality, students with visual impairments often require alternative methods for accessing materials, may experience challenges with social isolation, and could fall behind in their studies without proper support. Moreover, they are unlikely to observe color the way those with normal vision do, as evidenced by the fact that a student with color vision would not see a yellow paper under yellow light if the paper were originally black.
