Correct option is A

The sentence is a universal truth ("The Sun rises in the east"), and in indirect speech, we do not change the tense of universal truths.

• Option (a) correctly retains the present tense of "rises" and accurately transforms the direct speech into indirect speech.

• Option (b) uses "exclaimed," which is incorrect because there is no expression of surprise or emotion.

• Option (c) changes the tense to "rose," which is unnecessary since the statement is a universal truth.

• Option (d) introduces unnecessary details ("to everybody" and "will rise"), which are not in the original sentence.

• Thus, (a) is the correct answer.
