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

In C, parameters are always Question 1Answera.Passed by valueb.Passed by referencec.Non-pointer variables are passed by value and pointers are passed by referenced.Passed by value result

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.

In C, if you pass an array as an argument to a function, what actually gets passed? Value of elements in array First element of the array Base address of the array Address of the last element of array
