   Answer: (4) 2 and 4

   उत्तर: (4) 2 और 4

   Biofuels come from biomass that can be grown again, and hydropower uses flowing water that is constantly replenished by the sun-driven water cycle, so both are renewable. Fossil fuels and uranium are finite deposits in the earth that cannot be replaced on a human timescale, so they are non-renewable (nuclear power is low-carbon, but not renewable).
