To find the percentage of seniors who chose the prom theme "Into the Future," we can use the following formula:

\[ \text{Percentage} = \left( \frac{\text{Number of seniors who chose the theme}}{\text{Total number of seniors}} \right) \times 100 \]

From the table, the number of seniors who chose the theme "Into the Future" is 130. The total number of seniors is 200.

Now we can calculate the percentage:

\[ \text{Percentage} = \left( \frac{130}{200} \right) \times 100 = 65% \]

So, the answer is D. 65%.
