Answer:
Option B is the answer.
Step-by-step explanation:
Aida applied the distributive property to write the equivalent expressions given as
15 + 21 = 3(4 + 8)
But Aida made a mistake.
Since to get the common factor of 15 and 21 she did not divide these number of 3 correctly.
In simple words by division of 3 in 15 and 21 we get 5 and 7 instead of 5 and 8.
Therefore, option B is the correct answer.
