The question is asking to states the value of the z-score of a value that is 2.08 standard deviations greater than the mean and base on my research, the possible answer would be z-score is the number of standard deviations above the mean. If you are 5 standard deviations above the mean, that is defined as z = 5. If you are 1.1 standard deviations above the mean, that is defined as z = 1.1.
And so if you are 2.08 standard deviations above the mean
