Which of these is a tactual aid for visually challenged individuals?

Options

A. Talking calculator
B. Braille system
C. Audio book
D. Tape recorder

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a tactual aid for visually challenged individuals. "Tactual" refers to something that can be perceived through the sense of touch.

2. **Analyzing the Options**:
- **Option 1: Talking Calculator**: This device has keys that provide audio feedback when pressed. However, visually challenged individuals cannot identify the keys by touch alone, as they rely on audio cues rather than tactile feedback.
- **Option 2: Braille System**: The Braille system consists of raised dots that can be felt by touch. Visually challenged individuals can read and write using these tactile dots, making it a true tactual aid.
- **Option 3: Audiobook**: This is an audio format of books that can be listened to, but it does not provide any tactile feedback, so it is not a tactual aid.
- **Option 4: Tape Recorder**: Similar to audiobooks, tape recorders provide audio playback but do not offer any tactile interaction.

3. **Identifying the Correct Answer**: After analyzing all the options, the Braille system is the only option that provides a means of touch for visually challenged individuals.

4. **Conclusion**: The correct answer to the question is the Braille system, as it is specifically designed to be a tactual aid.

**Final Answer**: The Braille system is a tactual aid for visually challenged individuals.
