To find the percentile for 86, we need to use the following formula:

Percentile = [(Number of values below the given observation) / (Total number of observations)] x 100%

Number of values below 86 = 276

Total number of observations = 400

Percentile for 86 = [(276/400)] x 100% = 69%

Therefore, the answer is B) P69.
