On the basis of given table in question ,
Difference in production of toys of type B and C :
Year 2002 ⇒ 150 – 78 = 72 thousand
Year 2003 ⇒ 180 – 100 = 80 thousand
Year 2004 ⇒ 175 – 92 = 83 thousand
Year 2005 ⇒ 160 – 120 = 40 thousand
Year 2006 ⇒ 185 – 130 = 55 thousand
Total difference in production of toys of type B and C = 72 + 80 + 83 + 40 + 55 = 330 thousands
Number of types of toys = 5Correct Option: B
