Question

Statements: Some squares are circles.
No circle is a triangle. No line is a square.
Conclusions: I. No triangle is a square.
II. No line is a circle.

• A. if only conclusion I follows.
• B. if only conclusion II follows.
• C. if either conclusion I or conclusion II follows.
• D. if neither conclusion I nor conclusion II follows.
• E. if both conclusion I and conclusion II follow.

Answer 1

The correct option is D if neither conclusion I nor conclusion II follows.

Three cases are possible in this situation.

We will make the diagram that satisfy statements and if they are not following conclusions.

Some square are triangle in second diagram

Some line is circle in third diagram

Hence, Option D is correct.
