Question

emboldened each. The words may or may not be in their correct position. Rearrange the words if required and choose the correct option of arrangement from the options given below. The National Council of Educational Textbooks (A) and Training has decided to drop Mughal (B)  chapters on the Certain (C) Empire from Research(D).Solution
"Research" should be replaced with "textbook" because the context is about educational materials used for learning, which are textbooks. "Certain" should be replaced with "Mughal" to specify the empire in question, which is the Mughal Empire. With these corrections, the sentence now makes more sense: The National Council of Educational Research (A) and Training has decided to drop Certain (B) chapters on the Mughal (C) Empire from textbooks (D).
