Barbara used the distributive property to write an expression that is equivalent to 7 d + 63. Her work is shown below. The greatest common factor is 7 so 7 d + 63 = 7 (d + 63) What was Barbara’s error?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
