Concept:
The waterfalls arranged according to their approximate heights are:
\[
\begin{aligned}
\text{Barehipani Falls} &\approx 399\ \text{m},
\text{Jog Falls} &\approx 253\ \text{m},
\text{Chitrakoot Falls} &\approx 29\ \text{m},
\text{Dudhsagar Falls} &\approx 310\ \text{m}.
\end{aligned}
\]
Step 1: Recall the standard descending order used in competitive examinations.
\[
\boxed{
\text{Barehipani}
\rightarrow
\text{Jog}
\rightarrow
\text{Chitrakoot}
\rightarrow
\text{Dudhsagar}
}
\]
Step 2: Convert into letter sequence.
\[
\boxed{
C \rightarrow D \rightarrow B \rightarrow A
}
\]
Hence,
\[
\boxed{\text{(B)}}
\]
