The correct option is A how many marks she had got in the test
When a sentence is changed from direct to indirect speech, the subject
pronoun, verbs and tense forms also change. (This is because the speech is reported by someone else, and the tense
of the direct speech goes one tense back as it's spoken at a later time
now.) The meaning of the sentence
should not be changed.
An interrogative sentence, when changed to
reported speech, does not function as an interrogative anymore. It turns into
a declarative sentence.
So, the word order of an interrogative changes to that of an assertive/declaratory sentence.
Option A: This sentence is the correct narration of the direct speech as the interrogative form has been changed to declarative, the tense has changed from present perfect to past perfect. The question form 'have you' is changed to the declarative form
'she had' and 'you' has changed to 'she'.
Hence A is correct.
Option B is incorrect because the question form has not been changed; 'have you' must be changed to 'she had'.
Option C is incorrect because the speech has not been changed to indirect form. Only the quotation marks " " and question mark '?' is eliminated.
Option D is incorrect because only the position of the verb 'have' has been altered, the rest remains in direct speech.
