The best choice for controlling familywise error rate in this scenario would be to use a Bonferroni correction, which adjusts the alpha level of individual tests to account for the increased likelihood of making a Type I error across multiple tests.

The other options, such as Cramer's V test, Olive Dunn test, and Field Correction, are not appropriate for controlling familywise error rate in this context.
