To find out how much paper remained on the roll after Taylor made her sign, you can subtract the amount of paper she used (56 yards) from the total amount of paper she had (123 yards).
Remaining paper = Total paper - Used paper
Remaining paper = 123 yards - 56 yards
Remaining paper = 67 yards
None of the provided options (A, B, C, D) are correct. The remaining paper after Taylor made her sign is 67 yards.
