On which of the following can you find the Bureau of Energy Efficiency Star Label? 1. Ceiling fans 2. Electric geysers 3. Tubular fluorescent lamps Select the correct answer using the code given below.

Option (d) is correct because ceiling fans, electric geysers, and tubular fluorescent lamps are all included in the Bureau of Energy Efficiency’s (BEE) Standards and Labeling program, which assigns star ratings based on energy performance. Option (a) is the most tempting error if a candidate incorrectly assumes that smaller or older technologies like TFLs are excluded, whereas they were actually among the earliest products to receive mandatory labeling. The core concept tested is the identification of common household appliances regulated under India's energy efficiency framework to promote informed consumer choice and power conservation.
