Concept:
Placentation refers to the arrangement of ovules inside the ovary of a flower. It is an important characteristic used in plant morphology and classification.
Different plants possess different arrangements of ovules depending upon the structure of the ovary.
The important placentation types include marginal, axile, parietal and free central placentation.
To solve matching questions, we must know representative examples of each type.
Step 1: Understand marginal placentation.
In marginal placentation, the placenta forms a ridge along the ventral suture of the ovary.
Ovules develop along this ridge.
A common example is pea.
Thus
\[
A\rightarrow IV
\]
Step 2: Understand axile placentation.
In axile placentation, ovules are attached to a central axis and the ovary is divided into multiple chambers.
A common example is tomato.
Hence
\[
B\rightarrow II
\]
Step 3: Understand parietal placentation.
In parietal placentation, ovules are attached to the inner wall of the ovary.
The ovary usually remains unilocular.
Argemone shows parietal placentation.
Therefore
\[
C\rightarrow I
\]
Step 4: Understand free central placentation.
In free central placentation, ovules develop on a central axis but septa are absent.
Primrose is a classic example.
Thus
\[
D\rightarrow III
\]
Final matching becomes
\[
A-IV,\;B-II,\;C-I,\;D-III
\]
Therefore correct answer is
\[
\boxed{\text{Option (1)}}
\]
