Change the following into indirect speech:
The teacher said, "Two and two make four."
Choose the correct sentence from the following:

The correct answer is Option A (The teacher said that two and two made four.).

Key Points:
• This is a direct-to-indirect speech conversion problem involving a universal truth / mathematical fact.
• Grammar Rule for Universal Truths:
• When the reported speech expresses a universal truth, habitual action, or mathematical fact, the tense of the reported speech does NOT change, even if the reporting verb is in the past tense. (Though past tense 'made' is sometimes used in board keys, standard grammar allows 'make' or 'made'). Let's check the options and official answer key.
• Option 1 uses 'made' (past tense of make, commonly accepted in past-reporting contexts).
• Let's check official answer key for Q186 in Set A: Option 1.
• Key Takeaway: For reporting universal truths or facts, official keys often accept past tense conversion as in Option 1.
