Step 1: Understand the question:
The question asks for the two woolen floor rugs of Kashmir that carry chain stitch embroidery.
Step 2: Recall the craft:
Kashmir is famous for chain stitch work, called Crewel or Chain stitch.
The stitch is worked with a hooked needle called the ari.
It is used on shawls, garments and also on floor coverings.
Step 3: Identify the rugs:
Namda is a rug made of pressed (felted) wool, not woven.
Gabba is a rug made of old woolen cloth pieces, layered and stitched.
Both are decorated with bright chain stitch flowers and leaves. So the blanks are Namda and Gabba.
Step 4: Why the other options are wrong:
Option (A), Bird and Animal, are motifs and not rugs.
Option (B), Phiran and Shawl, are garments worn on the body.
Option (C), Aba and Odhani, are a cloak and a head cover. None of them is a floor rug.
Final Answer:
Chain stitch embroidery is done on the woolen floor rugs Namda and Gabba. This is option (D).
