Which of the following could replace 'digging out' as used in the passage?

Directions: Read the following passage carefully and select the most suitable option according to the corresponding number in the passage.

Arguing is very much in the human nature. Almost everyone does it. But everybody should understand that there is a right way and a wrong way to do it. Some people do it overtly by yelling while some others do it covertly without much hue and cry. You may think that the former is the right way and the latter is the wrong one. But the fact is that the method actually does not make any difference. Understand that you don't need to be furious to express your anger when you are not happy with something or someone. If you are angry, you don't need to throw things or break them or shout at people or end valuable relationships. This is regretful behaviour and hence not acceptable in a professional organisation.

Always avoid digging out issues of the past to use as a weapon against your colleague while talking about a present problem. Deal with the current issue first and if you have pent-up feelings from the past, put them off to be taken at an appropriate time in future. Don't get involved in unnecessary arguments initiated by attention seekers. There are people who like to argue because it gives them a feeling of being powerful. Such people normally drag others into unwanted arguments just for sake of getting some attention. Don't fall into their trap. Stay away from such people and save yourself from negative attention.
