Show answer & explanation
Correct answer: D
The statement 'Some erasers are not pencils' is an O proposition.
If this is false, the contradictory A proposition 'All erasers are pencils' must be true.
Consequently, the statement 'No erasers are pencils' (an E proposition) contradicts the truth of 'All erasers are pencils' and must be false.
