Invalid C Variable Name
The correct answer is option 'D' - int $main.
Explanation:
In C programming, variable names must follow certain rules and conventions in order to be valid. Let's analyze each option to understand why option 'D' is not a valid variable name.
1. int number:
- The variable name "number" is a valid C variable name.
- It starts with a lowercase letter and consists of only letters, numbers, and underscores.
- Therefore, option 'A' is a valid variable name.
2. float rate:
- The variable name "rate" is a valid C variable name.
- It starts with a lowercase letter and consists of only letters, numbers, and underscores.
- Therefore, option 'B' is a valid variable name.
3. int variable_count:
- The variable name "variable_count" is a valid C variable name.
- It starts with a lowercase letter and consists of only letters, numbers, and underscores.
- Therefore, option 'C' is a valid variable name.
4. int $main:
- The variable name "$main" is not a valid C variable name.
- C programming language does not allow variable names to start with special characters like '$'.
- Therefore, option 'D' is not a valid variable name.
Conclusion:
From the given options, option 'D' (int $main) is not a valid C variable name because it starts with a special character ('$'), which is not allowed in C programming.
The correct answer is option 'D' - int $main.

- It starts with a lowercase letter and consists of only letters, numbers, and underscores.
- Therefore, option 'B' is a valid variable name.
3. int variable_count:
- The variable name "variable_count" is a valid C variable name.
- It starts with a lowercase letter and consists of only letters, numbers, and underscores.
- Therefore, option 'C' is a valid variable name.
4. int $main:
- The variable name "$main" is not a valid C variable name.

Since only underscore and no other special character is allowed in a variable name, it results in an error.
