SPEECH. As per the question we have to change it into Direct Speech. The process of transformation as follows: 'asked' will be CHANGED into 'said to'. Comma and inverted COMMAS will be added. The given sentence is an example of an interrogative sentence with a question word. 'How' will be used as a conjunction because we know that in an interrogative sentence with a question word the question word itself is used as a conjunction. 'I' will be changed into 'you'.'Had paid' will be changed into 'did pay'. (indirect to direct speech)Therefore, as per the points mentioned above, we find that the correct answer is Option 1. Correct Sentence: She said to me, “How much did you pay for the mangoes?”Transformation of Imperative Sentences. 'Orders', 'Command', 'Request', 'Advice' are given in these kinds of sentences. Reporting VERB is changed into 'ordered, advised, requested, commanded, beg, forbade, suggested, proposed, assured, asked, reminded, warned, agreed, refused, promised', etc. Inverted Commas will be removed. And conjunction 'to/not to' will be used. Example: He said, "Mohan, PLEASE bring me my towel." (Direct Speech)He requested Mohan to bring him his towel. (Indirect Speech)
