Q: To capture the data of various resources ISRO developed one of the following sensors and deployed on IRS satellites :

ISRO's sensor is LISS, the Linear Imaging Self-Scanning Sensor.LISS cameras were developed by ISRO and flown from IRS-1A (1988) onwards, in successive versions (LISS-I to LISS-IV), to map land use, forests, water and crops for resource management.MSS and TM (Multispectral Scanner and Thematic Mapper) are sensors of the American Landsat satellites. AVHRR flies on NOAA weather satellites, and CZCS (Coastal Zone Color Scanner) flew on NASA's Nimbus-7. None was developed by ISRO.

Q: The 3 R's of resource management stands for

The 3 R's stand for Reduce, Reuse, Recycle.The order reflects the priority. Reduce the use of resources and the creation of waste in the first place. Reuse items as they are, again and again, before discarding them. Recycle materials such as paper, plastic, metal and crop residues into new products or compost when they can no longer be reused.The other options mix in words that are not part of the standard three: replace, refuse, rebuild, restore and reapply. 'Refuse' is sometimes added in longer lists of five or more R's, but the classic 3 R's are reduce, reuse and recycle.

Coal formed in this way from the plant matter of ancient swamp forests, and petroleum and natural gas are the other main fossil fuels.Solar energy is a renewable source of energy, not a fuel formed from fossils.
