Select the correct indirect form of the given sentence.

The mother said to her son," You must go to the Market and remain there till your father calls you back".

The mother told her son that he must go to the market and remain there till his father called him back.

The correct indirect form of the given sentence is:

The mother told her son that he must go to the market and remain there till his father called him back.

The other options are incorrect for the following reasons:

• The mother requested her son to go the market and remain there till his father calls him back. The reporting verb "requested" suggests that the mother was asking her son to do something, but the original statement is a command.
• The mother told her son to go to the market and remain there till your father calls him back. The pronoun "your" should be replaced with the pronoun "his", since the mother is speaking to her son.
• The mother told her son that he might go to the market and remain there till his father called him back. The modal verb "might" changes the meaning of the statement. The original statement is a command, but the indirect speech version suggests that the mother is giving her son a possibility.
