Answer: N

Explanation: Finding the new pressure group would involve looking into the Repetitive Dive Table, where we will be interested in finding the Residual Nitrogen time (RNT). The Residual Nitrogen Time value is the intersection of the pressure group D at 12m which according to the table is 26 min. This value '26' will be added to the next dive which is; 32 min + 26min = 58.

The intersection of value '58' at 12m is located in the table to find the next value of the pressure group. Which according to the table is N.

New pressure group is N

Explanation:

The Repetitive Dive table has to be checked, the residual nitrogen for the maximum depth of 38 feet as a "D" diver, then add that to the actual dive time to get the total nitrogen time. The total nitrogen time and the maximum depth of 38 feet would put you on a pressure group N.
