Which of the following is guideline that project managers should follow when responding to problems?Multiple choice question.They should greet bad news with verbal attacks.They should be predominantly concerned with finding out who is to blame for the problems.They should be concerned about preventing problems from happening again.They should involve in groupthink to solve problems.

The correct answer is: They should be concerned about preventing problems from happening again.

Here's why:

1. They should greet bad news with verbal attacks: This is not a good practice in project management or any professional setting. Verbal attacks can create a hostile environment and discourage team members from sharing important information in the future.

2. They should be predominantly concerned with finding out who is to blame for the problems: While it's important to understand the cause of a problem, focusing primarily on blame can create a negative culture and prevent the team from moving forward and finding a solution.

3. They should be concerned about preventing problems from happening again: This is the best practice. By focusing on prevention, project managers can learn from past mistakes and improve processes to avoid similar issues in the future.

4. They should involve in groupthink to solve problems: Groupthink, where decisions are made without critical evaluation of alternatives due to the desire for harmony, can lead to poor decision making. It's important to encourage diverse opinions and critical thinking in problem-solving.
