The correct answer is C. machine language.
Machine language is a set of instructions that a computer’s CPU can understand and execute directly. It is the lowest level of programming language, and it is made up of binary digits (bits), which are either 0 or 1. Each bit represents a different instruction, and the CPU can perform these instructions by reading and interpreting the bits.
FORTRAN, BASIC, and COBOL are all high-level programming languages. High-level languages are designed to be easier for humans to read and write than machine language. They are translated into machine language by a compiler or interpreter before they can be executed by the CPU.
E is not a correct answer because it is not a type of computer language.
