In the context of Binding which one of the following is incorrect?

This question was previously asked in
UGC NET 2022 Paper 1 Question Paper (22-Oct-2022) (Shift 2)
The correct answer is

Internal functions are known at link time

Binding is the association of a program entity with an attribute such as a type, an address or a code target. The standard binding times are compile time, link time, load time and run time, and each kind of information is fixed at a particular one of them.

Static binding is done at Compile Time — correct: static (early) binding is resolved by the compiler, e.g. non-virtual calls and the types of variables.

Absolute addresses are known at Load Time — correct: with relocatable code the loader fixes the final absolute addresses when the program is loaded into memory.

Internal functions are known at link time — incorrect: functions defined inside the same translation unit are already known to the compiler at compile time; it is external functions (other modules and libraries) whose references are resolved at link time.

Target of a function is known at runtime — correct for dynamic binding: for a virtual (overridden) method the actual function executed is selected at run time from the object’s type.

Internal functions are known at link time option is correct.
