Two statements are given, followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: No grass is a flower. All flowers are trees. Conclusions: I. Some trees are flowers. II. Some trees are grasses. III. No trees is a grass.?

Option 4 : Either conclusions II or III, and I follow

Statement I :No grass is a flower.

Statement II :All flowers are trees.

Conclusion I: Some trees are flowers → True

Conclusion II: Some trees are grasses → False(it is possible but not definite)

Conclusion III: No trees is a grass. → False(it is possible but not definite)

Here, Conclusion II and III makes complimentary pairs.

Hence, “Either conclusions II or III, and I follow” is the correct answer.
