Which one of the following primary sources of energy has recorded the highest growth in production in 2008-09 ?

Answer: A

In 2008-09 the highest growth was recorded by coal and lignite.

Compare each source with 2007-08.

\[ \text{Coal: } 8476 - 7926 = 550 \quad (6.9\%) \]

\[ \text{Hydro: } 5133 - 4944 = 189 \quad (3.8\%) \]

\[ \text{Natural gas: } 1265 - 1248 = 17 \quad (1.4\%) \]

Crude petroleum fell from 1429 to 1403, so it recorded negative growth. Coal leads on both the absolute and the percentage measure.
