Correct answer: (A) 1, 4 only

Explanation

The subalternate pair is "All plants are green organisms" and "Some plants are green organisms".

Statement 1 is the universal affirmative A, the superaltern.

Statement 4 is the particular affirmative I, its subaltern.

Subalternation links a universal to its corresponding particular of the same quality.

The truth of the universal A carries down to the particular I beneath it.

This vertical A-to-I relation makes Statements 1 and 4 subalternates.
