Choose the correct names for the program.

Insight: The task is to select appropriate names for a program from a given list. The correct names would likely follow programming naming conventions, such as using alphanumeric characters, underscores, or specific patterns, while avoiding special characters or unclear abbreviations that might cause issues or be difficult to interpret. The selection depends on context not provided in the image, but generally, names like 'wu_kvadrat', 's24', 'zadacha', and 'cena s nalogom' appear more conventional for programming than 'flower&picture' or single letters like 'z' or 'Щ' which might be ambiguous or problematic in some environments.
