- In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation technique? 1. It is a technique for cleaning up pollution by enhancing the same biodegradation process that occurs in nature. 2. Any contaminant with heavy metals such as cadmium and lead can be readily and completely treated by bioremediation using microorganisms. 3. Genetic engineering can be used to create microorganisms specifically designed for bioremediation. Select the correct answer using the code given below:

- With reference to agricultural soils, consider the following statements : A high content of organic matter in soil drastically reduces its water holding capacity. Soil does not play any role in the sulphur cycle. Irrigation over a period of time can contribute to the salinization of some agricultural lands. Which of the statements given above is/are correct ?
- Irrigation over a period of time can contribute to the salinization of some agricultural lands This statement is correct. Irrigation water, especially in arid and semi-arid regions, contains dissolved salts. When water is applied to fields, plants use some water, and much of it evaporates from the soil surface. The dissolved salts, however, are left behind. Without adequate drainage, these salts accumulate in the topsoil over time, leading to salinization, which reduces soil fertility and plant growth. 296. The long term solution of soil salinity and alkalinity is use of:
