Which of the following statements are true? Choose the most appropriate answer from the options given below.
- 1. Validity can never apply to any single proposition by itself
- 2. The concept of truth can apply to a single proposition
- 3. Propositions by themselves can be valid but not invalid
- 4. A proposition cannot be valid by itself though it can be invalid on its own
A4 only
B1 and 2 only ✓ Correct
C2 and 3 only
D2 and 4 only
Correct answer: (B) 1 and 2 only — Statements 1 and 2 are true, so the answer is 1 and 2.
Explanation
★Statements 1 and 2 are true, so the answer is 1 and 2.
★Validity is a property of arguments, not of single propositions.
★So validity can never apply to a single proposition by itself, making statement 1 true.
★Truth and falsity are properties of individual propositions.
★So the concept of truth can apply to a single proposition, making statement 2 true.
★Statements 3 and 4 wrongly attribute validity or invalidity to lone propositions, so they are false.
