You haven't provided any options for the identifiers. However, here are some general rules for valid identifiers in C:

1. The first character must be a letter or an underscore (_).
2. The rest of the identifier can consist of letters (lowercase or uppercase), digits (0-9), and underscores (_).
3. Identifiers in C are case sensitive.
4. Reserved words like int, float, etc., cannot be used as identifiers.

So, an invalid identifier in C could be anything that doesn't follow these rules. For example, "123abc" would be invalid because it starts with a digit. Similarly, "int" would be invalid because it's a reserved word.
