Statements
M $\$$ T; T @ K; K copyright D
Conclusions

II. K $\$$ M

• A. If only conclusion I is true
• B. If only conclusion II is true
• C. If either conclusion I or conclusion II is true.
• D. If neither conclusion I nor conclusion III is true.
• E. If both conclusions I and II are true.

Answer 1

The correct option is A If only conclusion I is true

Given statements are
M $\$$ T $\Rightarrow$ M < T ...(i)
T @ K $\Rightarrow$ T > K ...(ii)
K copyright D $\Rightarrow$ K = D ...(iii)
From all the statements, M < T > K = D
I. D $\$$ T $\Rightarrow$ D < T (True)
As, T > K = D
II. K $\$$ M $\Rightarrow$ K < M (False)
As, relation cannot be established.
