To determine the minimum surface interval required for the buddy team that performed the dives, it is crucial to analyze the two dives in relation to decompression limits and the accumulation of nitrogen in the body.

The first dive, which occurs at 100 feet for 17 minutes, likely places the divers in a shallower range regarding nitrogen saturation when they ascend to the second dive of 65 feet for 35 minutes. Utilizing a widely accepted dive table or dive computer for each of these depths and times reveals how much nitrogen is absorbed during each dive.

Following these calculations, the divers will need to account for a surface interval that allows them to safely off-gas the nitrogen absorbed during their dives. This involves considering both the depth of the dives and the duration, with more nitrogen remaining in the body after a deeper and longer dive.

The minimum required surface interval needs to take into account the "no-decompression limit" (NDL) and the accumulated nitrogen load. The computations indicate that the two dives collectively require a longer off-gassing period, which leads to the conclusion that a surface interval of 1 hour and 22 minutes is necessary for safe ascent and to reduce the risk of decompression sickness.

Thus, the correct answer reflects the calculated requirement to adequately
