Concept:
Habutai (also known as Habotai) is a plain woven silk fabric originally produced in Japan. It is one of the lightest and softest silk fabrics and is widely used in garments, scarves, linings, dresses, and decorative textiles.
The fabric is characterized by
• Smooth and soft surface,
• Lightweight construction,
• Plain weave structure,
• Excellent drape,
• Lustrous appearance.
The weight of silk fabrics is commonly expressed in grams per square metre (\(g/m^{2}\)) or in momme (mm). Habutai belongs to the lightweight category of silk fabrics.
Step 1: Understand the characteristics of Habutai fabric.
Habutai is manufactured using fine silk yarns in a plain weave.
Because of its lightweight construction, it is suitable for
\[
\begin{aligned}
&\bullet\ \text{Dress materials,}
&\bullet\ \text{Scarves,}
&\bullet\ \text{Linings,}
&\bullet\ \text{Decorative fabrics,}
&\bullet\ \text{Fashion garments.}
\end{aligned}
\]
Its low fabric weight provides excellent comfort and drape.
Step 2: Recall the standard fabric weight.
The commonly accepted fabric weight for Habutai silk is
\[
\boxed{
30-50\ g/m^{2}.
}
\]
This places Habutai among the lightest commercially produced silk fabrics.
Step 3: Examine each option.
Option (A): \(150-180\ g/m^{2}\)
This corresponds to comparatively heavy silk fabrics and not Habutai.
\[
\boxed{\text{Incorrect}}
\]
Option (B): \(200-250\ g/m^{2}\)
This represents very heavy silk fabrics used for upholstery and specialized applications.
\[
\boxed{\text{Incorrect}}
\]
Option (C): \(120-140\ g/m^{2}\)
This weight is much higher than that of lightweight Habutai silk.
\[
\boxed{\text{Incorrect}}
\]
Option (D): \(30-50\ g/m^{2}\)
This is the standard weight range of Habutai silk fabric.
\[
\boxed{\text{Correct}}
\]
Step 4: Write the final answer.
Hence, Habutai is a lightweight silk fabric having a weight of
\[
\boxed{
30-50\ g/m^{2}.
}
\]
Therefore,
\[
\boxed{\text{Option (D) is the correct answer.}}
