Answer 1

i think only first statement is correct ,becoz  in second it is saying that linker  replace absolute references in an object which is wrong linker always generate relocatable address adress

Answer 2

the linker produces absolute machine code,but here it says it replaces. So I is true only.Maybe

Answer 3

I think 3 is right anwer.

Answer 4

In computer science, a linker is a computer program that takes one or more object files generated by a compiler and combines them into one, executable program.

Computer programs are usually made up of multiple modules that span separate object files, each being a compiled computer program. The program as a whole refers to these separately compiled object files using symbols. The linker combines these separate files into a single, unified program, resolving the symbolic references as it goes along.

so only staement 1 is true
