Which data type is most suitable to store the value 'Yellow'?

Question

Text strings like 'Yellow' are textual data (a sequence of characters), so they should be stored in a string/short-text field rather than as numeric or Boolean values.

1. Relevant knowledge points and concepts
- Data types represent the kind of values a field can hold: Boolean (Yes/No) stores true/false; Number stores numeric values for calculations; Currency is a specialized numeric type for monetary amounts; Short text (string) stores words, letters, and short phrases.  
- Choose the data type that matches the nature of the value to preserve meaning and allow appropriate operations (search, sort, display).

2. Step-by-step reasoning
- Examine the value: 'Yellow' is made of letters and represents a color name — a word, not a quantity or a true/false condition.  
- Check each option:
  a. Yes/No (Boolean): stores only two possible values (true/false). 'Yellow' cannot be represented as Boolean without losing meaning.  
  b. Short text: designed for words and short phrases like color names. It preserves the exact string and allows text operations (filtering, display).  
  c. Number: used for integers/floats; 'Yellow' is non-numeric, so it cannot be stored as a number.  
  d. Currency: specialized numeric for money; 'Yellow' is not monetary.

3. Intermediate steps (validation)
- If you tried to store 'Yellow' in Number or Currency fields, the system would either reject it or force conversion (invalid). If stored in Yes/No, you'd have to map many colors to true/false arbitrarily, which is incorrect.

4. Why the correct answer is correct
- Short text directly matches the data’s type (a textual label). It preserves the content and allows standard text operations.

5. Why other options are incorrect
- Yes/No: only two states — unsuitable. Number/Currency: numeric only — unsuitable.

Conclusion: The most suitable choice is b. Short text (matches the provided correct answer).
