The statements below are followed by two conclusions labelled I and II. Assuming that the information in the statements is true, even if it appears to be at variance with generally established facts, decide which conclusion(s) logically and definitely follow(s) from the information given in the statements. Statements: All black are colours. All blue are colours. Conclusions: I. No blue is black. II. Some black are blue.?

Option 4 : Either conclusion I or II follows

As per the given statements, the least possible Venn diagram is as follows:

Conclusions:

I. No blue is black – False (It is possible but not definite).

II. Some black are blue – False (It is possible but not definite).

Since, both the conclusions form complementary pair so either of them must be true.

Hence, either conclusion I or II follows.
