What is the date when all Two Way salaries become fully guaranteed for the remainder of that season?

The correct answer relates to the specific timeline of Two Way salaries in the NBA. Two Way contracts are unique in that they allow players to spend time with both an NBA team and its G League affiliate. The salaries for these contracts initially may not be fully guaranteed, but there is a key date in the NBA calendar when this changes.

January 20 is significant because it marks the cutoff point in the NBA season when all Two Way salaries become fully guaranteed for the remainder of that season. Before this date, teams have more flexibility in terms of their Two Way contracts, but after January 20, the financial commitments become permanent, and players cannot have their contracts terminated without a financial penalty reflecting the guaranteed salary.

Other dates mentioned in the options do not align with this crucial point in the contract timeline. For example, December 31 and January 1 do not play a role in the guarantee status of Two Way contracts. Understanding this date is essential for both agents and players, as it influences decisions related to roster construction and salary cap management throughout the season.
