Choosing the individual whose name is first in alphabetical order is not a simple random sample because it is not based on a random selection process. It may be biased towards certain names depending on the population from which the sample is drawn. The other options involve a random selection process based on some criteria, such as phone number, name mixing, or student choice, which would more closely represent a simple random sample.
