When conducting a data flow analysis of following section of pseudo code: Declare C, F, Z Decimal Set Z = 32 Read F SetC = (F-Z) * 5/9 Free C, F. Z Print F Which of the variables utilized above has a potential anomalie?

Variable F is read from user input without validation, thus it can introduce unexpected values leading to potential anomalies in calculations involving C, which is based on F.

A suggests C and Z, but Z is initialized properly and has no issues. B incorrectly states that all variables are clean, disregarding input validation for F. C introduces irrelevant choices and lacks relevance to the specific code section.
