Choose the correct option to fill $?1$ and $?2$ so that the program below prints an input string in reverse order. Assume that the input string is terminated by a new line character. void reverse(void) { int c; if(?1) reverse(); ?2 } main() { printf("Enter text"); printf("\n"); reverse(); printf("\n"); }

(A)

$?1$ is $(getchar() != ’\setminus n’)$ $?2$ is $getchar(c);$

(B)

$?1$ is $((c = getchar() ) !=’\setminus n’)$ $?2$ is $getchar(c);$

(C)
