To find the cumulative frequency of the second class interval, we need to add up the frequencies of the first two intervals. The second class interval is "ea8a11_bc57_3400_9fff_11908fa574df_TB6468_00", which has a frequency of 15. The first class interval is "11ea8a_0110_11df_815e_12345abcdef0_TB6330_00", which has a frequency of 10. Therefore, the cumulative frequency of the second class interval is 10+15=25. The only choice that matches this answer is B.
