Test results can be considered:
                                          
in schools - as assessments of the final certification.
in universities  - as assessments of entrance exams.

Правильный  ответ  ⁿ4.  If you look carefully
look at the block diagram, you can see the following:  
                                          
                                          
                                          
The loop variable is the variable b.On-
initial value of  variable  cycle b=0.
Going to the operator that increases b, re-
occurs if condition 10<=b is NOT met -
i.e. subject to b<9. Print variable b
occurs  after  completion of the cycle. So
in the manner indicated  block diagram  unequivocally
corresponds to  program fragment, leading
given in the answer ⁿ4.
