The correct answer is C. cross compiler.
A cross compiler is a compiler that is used to compile code for a platform other than the one on which the compiler is running. This is useful for developing software for embedded systems or other platforms that do not have a native compiler.
An optimizing compiler is a compiler that attempts to improve the performance of the compiled code by performing optimizations such as inlining functions and eliminating dead code.
A one-pass compiler is a compiler that reads the entire source code file once and then produces the compiled code. This is in contrast to a multi-pass compiler, which reads the source code file multiple times.
A multi-pass compiler is a compiler that reads the source code file multiple times and produces the compiled code in multiple passes. This is done in order to perform certain optimizations that cannot be done in a single pass.
E is not the correct answer because it is not a type of compiler.
