Which of the following tools is the best use in ICT for visually impaired students?

Correct option is A

The correct answer is Text to speech.
For visually impaired students, the most beneficial ICT tool is text-to-speech as it allows them to access digital content by having it read aloud to them, making information readily available that would otherwise be difficult to read visually. 
Additional Information
· Text-to-speech: This software reads written text aloud, enabling visually impaired students to follow along with lectures, read online articles, and access educational materials. 
· Projection screen: While useful for visual presentations in general, it doesn't specifically address the needs of visually impaired students unless paired with accessibility features like captions or audio descriptions. 
· Social networking: Although important for social interaction and staying connected, social media platforms primarily rely on visual content, which may not be accessible to visually impaired users without additional features like captions or alt text. 
· Video conferencing: This can be beneficial for visually impaired students to participate in live discussions and interact with teachers and peers, but accessibility features like captions and screen reader compatibility are crucial for effective communication.
