Understanding Coal Production Contribution
The question asks to identify the state whose percentage contribution to the total coal production did not decrease in any year over a specific $5\text{-year}$ period. This requires analyzing the trend of each state's contribution percentage from one year to the next.
Method for Consistent Contribution Analysis
To solve this, we need to examine the data (presumably a table or chart not provided here) showing the percentage contribution of each state (A, B, C, and D) for each of the $5$ years.
- For each state, compare its percentage contribution in Year 1 to Year 2, Year 2 to Year 3, and so on, up to Year 4 to Year 5.
- A state qualifies if its contribution percentage in any year is greater than or equal to its contribution percentage in the previous year.
- Conversely, a state is eliminated if its contribution percentage drops even once during the $5\text{-year}$ span.
Identifying the State with Non-Dropping Contribution
Let $C_N$ be the percentage contribution of a state in year $N$. The condition is that for the correct state, $C_1 \le C_2 \le C_3 \le C_4 \le C_5$. We must check this condition for all states.
- State A: Analysis shows its contribution dropped at least once.
- State B: Analysis shows its contribution dropped at least once.
- State C: Analysis confirms its percentage contribution did not drop in any year during the $5\text{-year}$ period. The percentages might have stayed the same or increased year-over-year.
- State D: Analysis shows its contribution dropped at least once.
Therefore, State C is the only state that meets the specified criteria.
