Our wicket keeper says that he may not come for the practice today.

1. Maintaining tense and reporting verb:

   • The reporting verb "says" is in the present tense, so no backshift in the verb tense is needed. "May" remains "may."
   • The word "today" remains the same since the reporting verb is in the present.

2. Why this is correct: The sentence maintains the meaning and tense accurately in indirect speech.

Thus, the best option is: Our wicket keeper says that he may not come for the practice today.

OTHER OPTIONS

• "Our wicket keeper says that he might not come for the practice today": Incorrect because "might" suggests a backshift in tense, which is not required here since "says" is in the present tense.

• "Our wicket keeper said that he might not come for the practice that day": Incorrect because the reporting verb "says" is present tense, not past tense.

• "Our wicket keeper told me he won't come to the practice": Incorrect because "won't" and "told me" do not match the original sentence's meaning or tense.
