Which of the following option can be used as basic connectives

Options

A. "far" , "near"
B. "And", ''Or"
C. It is false
D. Is

Answer

To solve the question regarding which options can be used as basic connectives, we need to understand what basic connectives are in the context of propositional logic. Basic connectives are words that can join two or more independent sentences or propositions.

### Step-by-Step Solution:

1. **Identify the Options**: First, we need to identify the options provided in the question. Although the options are not listed in the question, we will assume common connectives such as "and", "or", "not", etc.

2. **Understanding Basic Connectives**: Basic connectives in propositional logic typically include:
- **Conjunction (AND)**: This connective is used to combine two propositions where both must be true for the combined proposition to be true. Symbolically, it is represented as \( p \land q \).
- **Disjunction (OR)**: This connective is used to combine two propositions where at least one must be true for the combined proposition to be true. Symbolically, it is represented as \( p \lor q \).
- **Negation (NOT)**: This is used to negate a proposition, indicating that if the proposition is true, the negation is false, and vice versa. Symbolically, it is represented as \( \neg p \).

3. **Evaluate Each Option**:
- If the option is "and", it is a basic connective.
- If the option is "or", it is also a basic connective.
- If the option is "not", it is a basic connective as well.
- If the option is "is" or "it is false", these are not connectives as they do not serve to join propositions.

4. **Conclusion**: Based on the evaluation, the correct options that can be used as basic connectives are "and", "or", and "not". Any option that does not fit this description (like "is" or "it is false") is not a basic connective.

### Final Answer:
The options that can be used as basic connectives are "and", "or", and "not".
