Given below are two statements: One is labelled as Assertion (A) and the other is labeled as Reason (R).
Assertion (A): A valid deductive argument with all true premises will lead to a true conclusion.
Reason (R): In a valid deductive argument, the conclusion follows from the premises with absolute necessity.

अभिकथन (A): सभी सत्य आधार-वाक्यों वाला एक वैध निगमनात्मक तर्क सत्य निष्कर्ष की ओर ले जाएगा।
कारण (R): एक वैध निगमनात्मक तर्क में, निष्कर्ष आधार-वाक्यों से परम अनिवार्यता के साथ निकलता है।

Correct answer: A. Both (A) and (R) are true and (R) is the correct explanation of (A)(A) और (R) दोनों सही हैं और (R), (A) की सही व्याख्या है
Explanation
An argument that is valid with all true premises is called a sound argument, and its conclusion must be true — so (A) is true. Validity means precisely that the conclusion follows from the premises with absolute (logical) necessity, so (R) is true and it is exactly the reason why (A) holds. Hence both are true and (R) correctly explains (A).जिस तर्क के सभी आधार-वाक्य सत्य हों और जो वैध हो, वह सुसंगत (sound) तर्क कहलाता है और उसका निष्कर्ष अनिवार्यतः सत्य होता है — अतः (A) सत्य है। वैधता का अर्थ ही यह है कि निष्कर्ष आधार-वाक्यों से परम (तार्किक) अनिवार्यता के साथ निकलता है, इसलिए (R) भी सत्य है और वही (A) का कारण भी है। अतः दोनों सही और (R), (A) की सही व्याख्या है।More Logical Reasoning questions
