Option (d) is correct.

Statements A "Some plants are non-fungi," B "Some plants are not fungi," and D "Some non-fungi are not not-plants" are logically equivalent.

Statement A and statement B express the same idea that there exist some plants that are not fungi.

Statement D can be rephrased as "Some things that are not fungi are not plants," which is equivalent to saying that there exists some non-fungi that are not classified as plants.

Statement C "Some fungi are plants" expresses a different idea, stating that there exist fungi that are classified as plants. This statement is not logically equivalent to statements A, B, or D.

Therefore, the correct answer is option (d) A, B, and D only.

विकल्प (d) सही है।
