Explaination

- Let's break down the options. The original statement was in direct speech about an event a month ago.

- Option 1: Correctly changes "today" to "that day," but incorrectly uses "has given" instead of "had given."

- Option 2: Correctly changes "today" to "that day" and "has given" to "had given," matching past narrative timing.

- Option 3: Incorrectly retains "today," which should be "that day," and "has given" should be "had given."

- Option 4: Incorrectly uses "is" and "today." Needs "was" and "that day," and "has given" should be "had given."
