Which of the following tasks could be attained using syntax trees in compiler design?
A. Type Checking
B. Code Generation
C. Code Optimization
D. Error Handling
Choose the correct answer from the options given below:

Correct option is A

Syntax trees play a crucial role in compiler design as they represent the hierarchical structure of the source code in a tree format. This structure is essential for understanding and processing the program's semantics, aiding in tasks like Type Checking, Code Generation, and Code Optimization. These tasks are critical in ensuring that the code is valid, optimized, and executable.
Information Booster: Syntax trees are beneficial in several compiler tasks. They contribute as:
1. Type Checking: The syntax tree helps the compiler check if the operations in the code are semantically valid. For instance, it verifies that operands and operators are compatible.
2. Code Generation: Syntax trees provide a structured representation, enabling the compiler to generate intermediate or target code from the source code systematically.
3. Code Optimization: Syntax trees allow the compiler to perform optimizations by rearranging or simplifying operations without changing the intended results, leading to more efficient code.
Additional Knowledge:
· Error Handling: Syntax trees aren't directly used for error handling. Instead, error handling is typically performed during lexical and syntactic analysis stages to catch and report any parsing errors.
· Control Flow Analysis: This task is handled using control flow graphs rather than syntax trees.
