Answer:
The correct answer is option B.
Explanation:
In a competitive industry there is no restriction on entry or exit of firms in the market. So, when in the short run the firms are enjoying super normal profits or positive economic profits, this would attract potential firms to join the industry in the long run.
As a result the industry supply will increase in the long run. The increase in supply would cause the price to fall. This would further contribute in reducing revenue and profit.
This process will continue till the profit is reduced to zero. If profit falls below zero, then firms incurring loss will exit the industry. Then again zero profits will be restored by reduction in supply and increase in price.
So, we can say that perfectly competitive firms will have zero economic profits or only normal profits in the long run.
Each establishment, whether small or big, government-owned or private companies, always have to backup their files in case of emergencies. As you make your backup plan, you must come across these five basic key questions:
1. Are you backing up all your data? You have to sort your files to be backed up because storage can be limited.
2. How often is your data backed up? You must make sure to back up your data on a regular basis, if not day-to-day.
3. Who is responsible for your backups? For big companies, it is too big of a task for one person to shoulder. Usually, this is tackled by a department, usually the I.T. Department.
4. Do your backups actually work? You should test regularly if these back ups actually work by restoring data files every now and then.
5. Do you have right backup checks and balances in place? The I.T Department tackling backup plans is one thing. But there should also be checks and balances so that you have a backup of your backup. It's better to be safe than sorry.

The correct answer is economic growth.
Explanation:
A production possibility curve or frontier shows the different combinations or bundles of two goods that can be produced using limited resources. The curve is concave because of increasing opportunity cost.
An outward shift in the production possibility curve shows an increase in the level of production. This can happen because of two reasons
,
- Increase in the quantity of resources available
, and
- Improvement in technology
Both of these factors will help in increasing the level of production. In other words, we can say that the outward shift in the production possibility curve shows economic growth.
