有以下程序：
struct STU
char name[10];
int num;
int Score,
；
void main()
struct STU s[5]= "YangSan",20041,703),"LiSiGuo",20042,580,
"WangYin",20043,680,"SunDan",20044,550,
"Penghua",20045,537，*p[5]，*t;
int i,j;
for(i=0;i＜5;i++) p[i]=＆s[i];
for(i=0;i＜4;i++)
for(j=i+1;j＜5,j++)
if(p[i]-＞Score＜p[j]-＞Score)
t=p[i];p[i]=p[j];p[j]=t;
printf("%d %d\n",s[1].Score,p[1]-＞Score);
执行后输出的结果是( )。
A．550 550
B．680 680
C．580 550
D．580 680
