Answer 1

The correct option is B Type checking

Type checking is an important component of semantic analysis.

Semantic analysis is the task of ensuring that the declarations and statements of a program are semantically correct, that their meaning is clear and consistent with the way in which control structures and data types are supposed to be used.

Type checking is a program analysis that verifies something about the types that are used in the program.
