Answer is 'D', Because comma operator used in the expression fclose (fp, fs, ft). The comma operator has left-right associativity. The left operator is always evaluated first, and the result of evaluation is discarded before the right operand is evaluated.

M getting segmentation fault even though m passing 1 parameter to it, can any 1 fix this problem?

We can use fcloseall(); then all the opened files will be closed.

Can we close some selected file at a time from the many no of files by use of fclose or any other method?

@Bhanu prakash.
You telling that it takes the first argument. Simply you are making fool to c compilers because any compiler may be turbo c or gcc it read from the right to left. Any it leave the extra parameter.

While fclose() read only one argument. Then we pass to the 3 files that time it will close 1 one.

To close all the files opened with fopen()at a time, we can use file function closeall(). This function has no arguments.

fclose() can close only one file at a time. If more than 1 argument than it will take only first and ignore rest.

The correct option id D coz..
syntax of fclose is-
#include <stdio.h>
int fclose( FILE *stream );
The function fclose() closes the given file stream, deallocating any buffers associated with that stream. fclose() returns 0 upon success, and EOF otherwise.
thats why when we give too much parameter inside fclose() it gives error-too many arguments to function 'fclose'.
