Consider the following statement about bioremediation:
I. It may be defined as any process that uses micro-organisms or their enzymes to return the environment altered by contaminants to its original condition.
II. Bioremediation may be employed in order to attack specific contaminants, such as chlorinated pesticides that are degraded by bacteria.
Which of the statements given above is/are correc?

{'bioremediation': [0, 0, 1, 0], 'contaminants': [0, 0, 1, 0], 'specific contaminants': [0, 0, 1, 0], 'bacteria': [4, 1, 2, 3], 'pesticides': [0, 0, 0, 2], 'environment': [2, 0, 0, 3], 'enzymes': [3, 0, 6, 3], 'process': [16, 0, 12, 37]}

The correct answer is option 3, which states that both statements I and II are correct.

Statement I is correct because bioremediation is defined as a process that uses microorganisms or their enzymes to restore the environment that has been altered by contaminants to its original condition. This process harnesses the natural ability of certain organisms to break down and degrade pollutants, such as oil, chemicals, or toxic substances, into less harmful forms.

Statement II is also correct because bioremediation can be targeted towards specific contaminants. For example, chlorinated pesticides can be degraded by bacteria, which means that bioremediation can be employed to specifically attack and remove these pollutants from the environment.

Therefore, both statements provide accurate information about bioremediation and its application in restoring environments contaminated with pollutants.
