What is a tawa commonly used for in Indian cooking?

Correct answer: To cook roti or paratha

The direct answer is option A: a tawa is commonly used to cook roti or paratha. A tawa is a broad, usually flat cooking pan. Its flat heated surface allows dough to be placed directly on it and cooked on both sides. It is also commonly used for dosa, chilla, or similar foods, but roti and paratha are the clearest answer here. Option A names a normal use of this utensil. Option B is wrong because clothes are washed in a vessel or washing area, not on a hot tawa. Option C is wrong because wood is cut with a saw or axe. Option D is wrong because water is filtered through a filter or clean filtering material. Remember: flat hot pan means tawa, and flat breads are its familiar use.
