Concept:
Each Five Year Plan in India was formulated with a distinct developmental priority based on the country's socio-economic needs. The major objectives of the given plans are:
• Second Five Year Plan (1956--1961) -- Industrialisation (Mahalanobis Strategy).
• Third Five Year Plan (1961--1966) -- Agricultural Development and attainment of self-sufficiency in food grains.
• Fourth Five Year Plan (1969--1974) -- Growth with Stability and Self-reliance.
• Sixth Five Year Plan (1980--1985) -- Improvement in Infrastructure along with poverty alleviation and modernization.
Step 1: Match each Five Year Plan with its major objective.
\[
\begin{aligned}
\text{Second Plan} &\rightarrow \text{Industrialisation (D)},
\text{Third Plan} &\rightarrow \text{Agricultural Development (C)},
\text{Fourth Plan} &\rightarrow \text{Self-reliance (B)},
\text{Sixth Plan} &\rightarrow \text{Improvement in Infrastructure (A)}.
\end{aligned}
\]
Step 2: Arrange the objectives in the required sequence.
\[
\boxed{
\text{D}
\;\rightarrow\;
\text{C}
\;\rightarrow\;
\text{B}
\;\rightarrow\;
\text{A}
}
\]
This corresponds to
\[
\boxed{\text{(B) D, C, B, A}}
\]
