- P – Competence: Refers to the native speaker's ability to intuitively understand and generate language (related to native speaker intuition).
- Q – Performance: Refers to the actual use of language in communication, as opposed to the underlying knowledge of the language.
- R – Sense: Refers to the specific meaning of an expression in relation to the context or situation.
- S – Reference: Refers to the relationship between an expression and its real-world entity or referent.
Step 2: Analyzing the options.
- (1) P – ii, Q – iv, R – iii, S – i: This sequence does not match the correct definitions.
- (2) P – iv, Q – ii, R – iii, S – i: This sequence is incorrect as it does not match the correct relations.
- (3) P – ii, Q – iv, R – i, S – iii: This sequence is incorrect as it does not match the correct relations.
- (4) P – iv, Q – ii, R – i, S – iii: This is the correct sequence, matching the terms with their appropriate descriptions.
Step 3: Conclusion.
The correct answer is (4), as this sequence correctly matches the terms with their descriptions.
