“We’ll go for an outing tomorrow,” said Laila’s father, “so you had better complete your homework this evening.”

The correct answer is A.

Laila’s father is telling her to complete her homework that evening as they would be going for an outing the next day. This is evident in the use of the present tense verb “tell” in the sentence. The sentence also uses the word “better,” which suggests that Laila’s father is giving her a strong suggestion to complete her homework.

Option B is incorrect because it uses the past tense verb “told.” This suggests that Laila’s father told her to complete her homework at some point in the past, but it is not clear when.

Option C is incorrect because it uses the present tense verb “tells.” This suggests that Laila’s father is telling her to complete her homework right now, but it is not clear when they are going on the outing.

Option D is incorrect because it uses the past perfect tense verb “had told.” This suggests that Laila’s father told her to complete her homework at some point in the past before they went on the outing. However, the sentence does not specify when Laila’s father told her to complete her homework.
