The year wise total production of minerals and metals is as shown below:-
$2005=69+91+71+15+100=346$
$2006=75+88+75+18+120=376$
$2007=81+97+79+21+102=380$
$2008=98+107+88+25+131=449$
$2009=93+110+92+24+143=462$
$2010=99+116+97+20+154=486$
$2011=105+122+103+125+103=518$
The y-o-y increase in the total production of minerals and metals is as shown below:-
$2006=376-346=30$
$2007=380-376=4$
$2008=449-380=69$
$2009=462-449=13$
$2010=486-462=24$
$2011=518-486=32$
Thus, year 2008 has witnessed highest absolute increase in total production of minerals and metals.
Hence, option B is the correct answer.
