Select the correct indirect form of the given sentence.
The maid said, "Shall I open the door?"

Correct option is C

Direct speech: The exact words of the speaker are quoted, usually within inverted commas (e.g., She said, "I am tired.").
Indirect speech: The speaker’s words are reported without quoting exactly, often with changes in pronouns, tense, and word order (e.g., She said that she was tired.).
The correct indirect speech form is (c) The maid asked if she should open the door.
Explanation:
This is a yes/no type interrogative sentence in direct speech using the modal "shall". When converting to indirect speech:
· "Shall I" (in a question) becomes "if she should" in indirect form.
· The reporting verb changes from said to asked since it's a question.
· Pronouns and tenses must be adjusted appropriately:
· "I" → "she" (referring to "the maid")
Structure:
· Direct: Subject + said/asked + “Shall I + verb?”
· Indirect: Subject + asked + if + subject + should + verb
Example:
Direct: She said, "Shall I call him?"
Indirect: She asked if she should call him.
