Explanation

Bioremediation is a beneficial technique for addressing pollution issues because it uses natural biodegradation processes to clean up contaminants. It is particularly effective in treating heavy metals like cadmium and lead using microorganisms. Furthermore, genetic engineering can be employed to develop microorganisms tailored for bioremediation. The correct advantages associated with bioremediation are options 1 and 3, as it leverages natural processes for pollution cleanup and can be enhanced with genetically engineered microorganisms.
