In the illustrated algorithm flow chart, the value of the output s is () A.52B.53C.54D.5

The first cycle gets S=3 and I = 4；; The second cycle gets S=3+4=7 and I = 5；; The third cycle gets S=7+5= 12, I = 6；;

The fourth cycle gets S= 12+6= 18, and I = 7；; The fifth cycle gets S= 18+7=25 and I = 8；; The sixth cycle gets S=25+8=33 and I = 9；;

The seventh cycle gets S=33+9=42, I =10; In the eighth cycle, we get S=42+ 10=52 and i= 1 1.

At this time, the conditions in the judgment box are met, and the output is executed.

So choose a.
