**Question:**

When compiling our C code into assembly, in which stage will we receive an error if we tried to return a double instead of an int?

**Options:**

- ○ A. Preprocessing
- ○ B. Lexing
- ○ C. Parsing
- ○ D. Type checking
- ○ E. Code generation

**Explanation:**

In C programming, the process of compiling code into assembly involves several stages. An error from trying to return a double instead of an int is typically caught during the **type checking** stage. This is because type checking involves ensuring that the data types in your code are compatible and used correctly, which would identify mismatches like attempting to return an incorrect data type. 

The answers provided in the multiple-choice question help understand the different phases of the compilation process, each with its unique responsibilities and checks:

- **A. Preprocessing** involves handling directives and macros before compilation.
- **B. Lexing** focuses on converting the code into tokens.
- **C. Parsing** constructs a syntactical structure from the tokens.
- **D. Type checking** validates data type usage and compatibility.
- **E. Code generation** transforms validated structures into assembly code.
