Change the following statement into indirect speech :
 She said, “Please do not disturb me in my studies.”
a)She said that please do not disturb me in my studies.
b)She requested not to disturb her in her studies.
c)She suggested not to disturb her in her studies.
d)She proposed not to disturb her in her studies.

Hint: To answer the question, one needs to have a crystal clear understanding of direct and indirect speech. Direct speech is when someone or a situation is quoted verbatim, while indirect speech is when it is told from a third-person perspective.

Complete step-by-step answer:

Direct speech means, the speaker or the event quotes, as it is. While indirect speech is told like a narration. The given statement sounds like the person requested something. The word ‘please’ suggests that it is a request and not a suggestion or proposal or assertion. Option ‘a’, says “she said…” which is incorrect, as we discussed, it is not an assertion. It is an incorrect option. Option ‘b’, “she requested…”, aligns with the explanation given above, hence it is the correct option. Option ‘c’, “she suggested….”, she did not suggest, that would have included words like “should”, “may”, hence the option is incorrect. Option d, “she proposed…”, again, she did not propose, but requested. Hence this is an incorrect choice as well. Option b is the correct choice.

Note: To answer the given question, one must have an understanding of direct and indirect speeches and to be able to understand the tone, clearly.
