Answer to the first question::::
The option a is correct.
As we know the syntax of function declaration in C.It is necessary to mention the data type of parameter.otherwise by default the data type will be void and that is not what we want as argc is of integer type and argv is an array and SO option b doesnt follow the syntactical rules of functn declaration and it is incorrect.
Function declaration doesnt contain body of the function which is given in option C. So, option c is also incorrect.
Answer to the second question:::::
option c-redeclaration of a.
one of the parameters of the function is a and the local variable of the function is also a. the value of parameter will be overwritten by value of local variable.
So the error is in redeclaration of a.
