In this paper we settle the two-dimensional case of a conjecture involving unknown semialgebraic functions with specified smoothness. More precisely, we prove the following result: Let β be a semialgebraic bundle with respect to πΆ^{π}_{πππ}(β2, βπ·). If β has a section, then it has a semialgebraic section.
