Answer:
b) you ironed
Step-by-step explanation:
option b, “you ironed” is the correct option, because it sounds the most correct out of all of the other options; option a, “been ironing”, only works if “you” is in front of “been”, otherwise, it doesn’t sound right; options c and d mention “the clothes”, and since “the clothes” is already in the provided sentence, these options end up sounding redundant
