Concept:
Gaganendranath Tagore (1867--1938) was one of the pioneers of modern Indian art. His artistic career passed through distinct phases:
• Puri Landscapes -- Early works inspired by visits to Puri.
• Chaitanya Series -- Religious and devotional paintings influenced by Vaishnavism.
• Caricatures -- Satirical drawings criticizing colonial society and contemporary life.
• Portrait Sketches -- Later works emphasizing expressive portraiture and sketches.
Step 1: Arrange the artworks chronologically.
The correct order of execution is
\[
\boxed{
\text{Puri Landscapes}
\rightarrow
\text{Chaitanya Series}
\rightarrow
\text{Caricatures}
\rightarrow
\text{Portrait Sketches}
}
\]
Step 2: Match with the given letters.
\[
\begin{aligned}
\text{Puri Landscapes} &\rightarrow B,
\text{Chaitanya Series} &\rightarrow C,
\text{Caricatures} &\rightarrow D,
\text{Portrait Sketches} &\rightarrow A.
\end{aligned}
\]
Thus,
\[
\boxed{B,\ C,\ D,\ A}
\]
Hence,
\[
\boxed{\text{(B)}}
\]
