Q. Choose a correct statement about C file operation program?

int main()
{
    FILE *fp;
    char ch;
    fp=fopen("readme.txt","r");
    while((ch=fgetc(fp)) != EOF)
    {
        printf("%c",ch);
    }
}

• (A) FOPEN opens a file named readme.txt in Read Mode ("r).
• (B) EOF is End Of File. ch==EOF checks for end of file and while loop stops or exits.
• (C) FGETC(fp) is a function that returns one character and cursor goes to next character.
• (D) All the above
