A translator used in low level language is ______

Answer: C) Assembler

Low-level languages primarily refer to assembly language (and machine language). An assembler is the translator that converts assembly language mnemonics into machine code (object code).

A compiler translates high-level language source code into machine code (or intermediate code).
An interpreter executes high-level language code line by line without producing a separate machine-code file.

Neither compilers nor interpreters are the standard translators for low-level (assembly) languages, so the correct choice is Assembler.
