Step 1: Understand the question:
The question is about tie dyed textiles from Rajasthan. It asks for the technique that gives a multi-coloured resist dot pattern.
Step 2: Recall the Lipai technique:
In Rajasthan the dots are first made by tying the cloth with thread.
In the Lipai technique, different dyes are applied by hand on the tied portions.
Each tied area takes its own colour. The result is a multi-coloured dot pattern.
Step 3: Why the other options are wrong:
Etching: this is a printing or discharge style. It removes colour. It is not a tie dye method.
Dot: this describes the shape of the motif, not the name of the technique.
Stamping: this is block printing, where a carved block is pressed on the cloth.
Final Answer:
The multi-coloured resist dot pattern is produced by the Lipai technique. The correct option is (B).
