The assumption of independence for the one sample t test calls for random selection of the sample from the population. It is important that the sample is representative of the population and not biased towards any particular subgroup. The other options (equal sample sizes, random assignment, and sample size greater than 30) are assumptions for different types of hypothesis tests, but not for the one sample t test specifically.
