Question

Given below are two statements:
Statement-I: To obvert a proposition, we change its quality and replace the predicate term with its complement.
Statement-II: Obversion is valid for any standard form categorical proposition.
In light of the above statement, choose the correct answer from the options given below:

• A. Both statement I and statement II are true
• B. Both statement I and statement II are false
• C. Statement I is true but statement II is false
• D. Statement I is false but statement II is true

Hint:

When analyzing categorical propositions, remember that obversion only applies to certain forms of propositions.

Answer 1

The Correct Option is C

Statement I is correct because obversion involves changing the quality of a proposition and replacing the predicate term with its complement. However, Statement II is incorrect because obversion is only valid for some categorical propositions (specifically A, E, I, and O forms), not all standard form categorical propositions. Hence, the correct answer is "Statement I is true but statement II is false."
