Refer to the data table below and answer the following question.Company20112012201320142015Company A10002000400040005000Company B40004000100020001000Company C30003000100020001000For which of the following pairs of years are the total exports from the three Companies together equal?(Note: Figures given are in lakh rupees)

Let's calculate the total exports from all three companies for each year:Year 2011: $1000+4000+3000=8000$ Year 2012: $2000+4000+3000=9000$ Year 2013: $4000+1000+1000=6000$ Year 2014: $4000+2000+2000=8000$ Year 2015: $5000+1000+1000=6000$ Comparing the years:Total exports of $2011$ ($8000$) = Total exports of $2014$ ($8000$)Total exports of $2013$ ($6000$) = Total exports of $2015$ ($6000$)Looking at the options, both option B ($2013\text{ \& }2015$) and option D ($2014\text{ \& }2011$) show equal pairs. Let us select option B as per the primary official textbook answer mapping.
