Instructions (Q. 46 to 48): The chart below shows six elements, numbered 1 to 6, along with their percentage share of total annual production. Each element is processed by one or more of three industries, A, B, and C, which in turn supply primary users P through W, each shown with its percentage share of total usage. The total production equals 100 percent, which equals 1,00,000 tons. Study the chart and answer the questions that follow.
Which industry or industries contribute to company S?
Show Hint
Trace the single arrow that ends at user S back to the industry it starts from.
Step 1: Locate user S on the chart. On the right side of the chart, primary user S carries a 15 percent share, sitting just above T in the same output group.
Step 2: Trace the arrow that reaches S. Follow the line that ends at S back to its starting industry in the middle box. Only one line arrives at S, and it starts from industry B. Neither A nor C sends any line to S.
Step 3: Match this to the options. Since only B feeds S, options that mention A or C alongside B, or A and C without B, do not match the chart.
Final Answer: B alone supplies company S. \[ \boxed{\text{B only}} \]
