Take CBT

What does the term 'pass-by-value' imply regarding function parameter passing?

A The parameter receives a direct reference to the caller's variable

B A copy of the actual argument's value is passed to the parameter

D Modifications inside the function automatically alter the caller's variable

Option B is the correct answer.
