The correct answer highlights that Greg and Sue are required to file a California return because their combined gross income exceeds the state's threshold for filing. California has established income thresholds that determine whether taxpayers must file a return, based on their filing status, age, and income level.

In this case, with a combined gross income of $64,500, Greg and Sue surpass the income threshold set by California for their filing status. This reinforces the requirement for them to file a tax return, as it is the income that primarily dictates the obligation to file.

Understanding this requirement is crucial, as it helps taxpayers navigate their filing obligations correctly and ensures they comply with state regulations. The other options either reflect incorrect interpretations of age-related filing requirements or lack consideration of gross income as a decisive factor in the obligation to file.
