Explanation:

Total Oil Used = House Hold + Transport + Industrial + Suburban

Total Oil Produced = Total Oil Used + Oil Production Loss

​​​​​​​

Now, Oil used for House Hold as a percentage of Total Oil Used:

During 1998 = $\frac{22}{2870}$ × 100 ≈ 0.77%

During 1999 = $\frac{22}{2834}$ × 100 ≈ 0.78%

During 2000 = $\frac{20}{2920}$ × 100 ≈ 0.68%

During 2001 = $\frac{22}{3262}$ × 100 ≈ 0.67%

On observing the data given in the question and the table of the set, we can conclude that the correct statement is 4.
Hence, option (d).
