Concept:
The Indian Constitution borrowed many important features from the constitutions of different countries.
•
Step 1:
India adopted the Parliamentary System of Government from Britain.
Therefore:
\[
A \rightarrow II
\]
•
Step 2:
Fundamental Rights in India were inspired by the US Constitution.
Therefore:
\[
B \rightarrow I
\]
•
Step 3:
Directive Principles of State Policy (DPSP) were borrowed from Ireland.
Therefore:
\[
C \rightarrow III
\]
•
Step 4:
The concept of Federation with a Strong Centre was borrowed from Canada.
Therefore:
\[
D \rightarrow IV
\]
•
Step 5:
The correctly matched sequence is:
\[
A-II,\ B-I,\ C-III,\ D-IV
\]
\[
\boxed{\text{(1) A-II, B-I, C-III, D-IV}}
\]
