The correct Answer is:
To solve the question regarding the usefulness of GM (Genetically Modified) plants, we can analyze each option step by step: 1. **Understanding GM Plants**: GM plants are organisms whose genetic material has been altered using genetic engineering techniques. This modification can lead to various benefits in agriculture. 2. **Analyzing Option A - Crop Yield**: GM plants have been engineered to increase crop yield. This means that they can produce more food per unit area compared to non-GM plants. Therefore, this option is correct. 3. **Analyzing Option B - Reduce Post Harvest Loss**: GM plants can also be designed to have traits that reduce post-harvest losses. This can include resistance to pests and diseases, which helps in maintaining the quality of the crop after it has been harvested. Hence, this option is also correct. 4. **Analyzing Option C - Make Crops More Tolerant to Stresses**: GM plants can be modified to be more tolerant to environmental stresses such as drought, salinity, and extreme temperatures. This allows them to survive and thrive in conditions that would otherwise be detrimental, making this option correct as well. 5. **Analyzing Option D - All of These**: Since options A, B, and C are all correct, it follows that option D, which states "all of these," is also correct. **Conclusion**: The correct answer is **d) all of these**. ---

First read a passage and then answer the questions following that passage. Soil scientists have shown that the soil teems with millions of living things, many of them useful, others harmful. The living things which are useful include earthworms and various kinds of bacteria. Earthworms loosen the soil and so enable air and water to enter it. Bacteria, which are microscopic living things break down dead plants and animals and make humus, or take nitrogen from the air and change it into substances that plants use. The living things that do harm include other bacteria and fungi which cause diseases. Other harmful things are pests such as wire worms which feed on the roots of grass and other plants. While the farmer can usually keep weeds in check by careful cultivation, this alone may not protect his crops from insects, pests and diseases. Nowadays, however, he is much better able to control these enemies. He may plant. specially resistant types of seeds or he may keep the pests and diseases in check with chemicals. With better seeds farmers have been able to increase their crop yield . They can grow crops that ripen more quickly and have a stronger resistance to disease, frost or drought. The farmers today can also select seeds
