The correct choice is: "True"

Explanation:

• An assembler is a program that translates assembly language code, which is a symbolic representation of machine instructions, into binary machine language instructions that can be executed by a computer's processor. The purpose of an assembler is to produce a one-to-one correspondence between the assembly language source program and the machine language object program.
• The assembler takes the assembly language source program as input and processes it to generate the corresponding binary machine code. Each assembly language instruction is mapped to its equivalent machine language instruction, resulting in a direct correspondence between the two. The assembler performs tasks such as lexical analysis, parsing, symbol resolution, and code generation to accomplish this translation process.
• The machine language object program generated by the assembler can be directly executed by the computer's processor, as it contains the binary instructions that the processor can understand and execute.

Hence, an assembler does indeed produce the binary machine language equivalent of an assembly language program, establishing a one-to-one correspondence between the assembly language source program and the machine language object program.
