    if first line is like below
    typedef char* Str_typed;
    then answer is I

    That means in the second line Str_typed is a character pointer.
    Can you tell me what does char* means in your 5th line.

    if there is no space between * and Str_typed then below is answer
    typedef can be used for renaming the predefined keywords.
    typedef char *Str_typed;
    this means for declaring character varibles instead of using char we can use *Str_typed
    in the code Str_typed s1, s2
    so in above code Str_typed is undefined it will give error.
    if there is space between * and Str_typed then below is answer
    typedef char * Str_typed;
    if we have space between * Str_typed then the above meaning is for declaring character pointer we can use Str_typed . In this case first option is correct.
