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:

To determine which of the conclusions follow from the given statement, let us analyze the relationships step-by-step.

The given statement is:
$B\le F=J\le N<R\le V<Z$

Let us evaluate each conclusion based on this statement:

Conclusion I: $F>R$
From the statement, we can extract the relationship between $F$ and $R$:
$F=J\le N<R$
This simplifies to:
$F\le N<R$
Since $F$ is less than or equal to $N$, and $N$ is strictly less than $R$, it follows that:
$F<R$
Therefore, the conclusion $F>R$ is false.

Conclusion II: $B\le N$
From the statement, we can extract the relationship between $B$ and $N$:
$B\le F=J\le N$
This simplifies to:
$B\le F\le N$
Combining these inequalities gives:
$B\le N$
Therefore, the conclusion $B\le N$ is true.

Since only conclusion II is true, the correct option is "If only conclusion II is true".
