Statements: B ≤ F = J ≤ N < R ≤ V < Z
Conclusions:
I. F > R
II. B ≤ N
In this question, the relationship between different element is shown in the statements. The statements are followed by two conclusions. Give answer:

The correct answer is If only conclusion II is true.

To determine the validity of the conclusions, we analyze the relationship between the elements given in the statement:

$B\le F=J\le N<R\le V<Z$

Analysis of Conclusion I (F > R):

From the given statement, the relationship between F and R can be established as:

$F=J\le N<R$

This simplifies to:

$F<R$

Since F is strictly less than R, the conclusion
$F>R$
is false.

Analysis of Conclusion II (B ≤ N):

From the given statement, the relationship between B and N is:

$B\le F=J\le N$

Since $F=J$, we can combine these inequalities to get:

$B\le N$

This matches Conclusion II exactly, so Conclusion II is true.

Therefore, only conclusion II is true.
