On which of the following can you find the Bureau of Energy Efficiency Star Label?1.Ceiling fans2.Electric geysers3.Tubular fluorescent lampsSelect the correct answer using the code given below

1. A

   1 and 2 only

   Ceiling fans and electric geysers both carry BEE star labels, but tubular fluorescent lamps were among the earliest labelled products. Stopping at 1 and 2 omits TFLs.

2. B

   3 only

   Tubular fluorescent lamps alone would ignore fans and geysers, which are also on the Standards & Labelling schedule. 3 only is incomplete.

3. C

   2 and 3 only

   Geysers and TFLs without ceiling fans would drop a product that BEE has labelled (mandatory for many fan ratings). 2 and 3 only is not the key.

4. D

   1, 2 and 3

   The Bureau of Energy Efficiency’s Standards & Labelling programme covers ceiling fans, electric geysers and tubular fluorescent lamps, among other appliances. All three can carry the star label, so (d) is the official key.

Summary. Official key is (d) 1, 2 and 3. BEE, set up under the Energy Conservation Act, 2001, runs a star-label scheme so buyers can compare energy use. Lighting (including TFLs), fans and water heaters have long been on the labelled list, some under mandatory labelling. The question is not which is currently the most efficient technology (LEDs have overtaken TFLs) but where the label can be found. All three products qualify.
