What does 'pass by value' mean in C?*1 pointPassing a copy of the argumentPassing the argument directlyPassing the memory addressPassing the variable type

n the following code,int f(int *a) {  *a  = 20;}int main() { int m = 30; f(&m);}a.The parameter passing is "pass by address", and the "address of m" is passedb.Parameter passing is by value, the value passed is "address of m", and copied into the argument *a c.Parameter passing is by value, the value passed is "m", and copied into the argument a d.Parameter passing is by value, the value passed is "address of m", and copied into the argument ae.The parameter passing is "pass by reference" and variable a is a reference to variable m.

Which of the following is required to pass an argument by reference?Select one:a.swap(2,3); Pass the values as literalsb.swap(&x, &y); Send the address of the variable as an argumentc.&a, &b = swap(x,y); It must be returned to a variable as an addressd.void swap(int &x, int &y); Receive the variables in the parameter as an address
