Step 1: Collect XH–B1 inequalities.
From the statements for paper B1:
\[
\begin{aligned}
\text{(i)}\ &\text{Bw} < \text{Ct}
\text{(ii)}\ &\text{Dv} > \text{Ct}
\text{(iii)}\ &\text{Em} < \text{Dv}, \text{Em} > \text{Fu}
\text{(iv)}\ &\text{Ar} < \text{Em}, \text{Ar} > \text{Fu}
\end{aligned}
\]
Step 2: Chain what we can.
From (iv) and (iii): $\text{Fu} < \text{Ar} < \text{Em} < \text{Dv}$.
From (ii): $\text{Ct} < \text{Dv}$.
From (i) and (ii): $\text{Bw} < \text{Ct} < \text{Dv}$.
Step 3: Decide the topper in B1.
Every candidate is strictly below Dv:
- $\text{Ct} < \text{Dv}$ (given), hence $\text{Bw} < \text{Ct} < \text{Dv}$.
- $\text{Em} < \text{Dv}$ (given), and $\text{Ar} < \text{Em}$, $\text{Fu} < \text{Ar}$.
Therefore, \(\boxed{\text{Dv is the highest in XH–B1}}\).
