The answer is: B
Explanation
The correct option is B: She says that she eats a mango a day.
When changing direct speech to indirect speech (also known as reported speech), we follow certain rules. In this case:
The reporting verb "says" is in the present tense, so the tense of the verb in the reported speech does not change.
The pronoun "I" changes to "she" to match the subject of the reporting verb.
The verb "eat" remains in the present tense, "eats," because the reporting verb is in the present tense.
So, the direct speech "She says, 'I eat a mango a day'" is correctly transformed to indirect speech as "She says that she eats a mango a day."
The other options do not fit:
A: She said that she ate a mango a day uses the past tense "said" and changes the verb tense incorrectly.
C: That she eats a mango a day was said by her is an awkward and incorrect construction.
D: She said that she eats a mango a day
