Choose the option that is the correct indirect form of the sentence.

My mother said, "I am meeting your father today."

My mother said that she was meeting my father that day.

The correct indirect form of the sentence is:

My mother said that she was meeting my father that day.

The other options are incorrect because they do not follow these rules:

• My mother said that she were meeting my father that day. - This sentence uses the subjunctive mood for "was," which is not necessary in indirect speech.
• My mother says that she was meeting my father today. - This sentence uses the present tense for "says" and "was meeting," which is incorrect in indirect speech.
• The mother said that she has been meeting my father that day. - This sentence changes the subject from "My mother" to "The mother," and it also changes the tense from the past tense to the present perfect tense, which is incorrect in indirect speech.
