如下程序片段执行后，SVEC的值是( )SIGNAL S1，S2：STD_LOGIC;SIGNAL SVE
C:STD_LOGIC_VECTOR(0 TO7);…PROCESS(S1,S2)VARIABLE V1,V2:STD_LOGIC;BEGIC V1:=’0’; V2:=’0’;S1<=’0’;S2<=’0’;SVEC(0)<=V1; SVEC(1)<=V2;SVEC(2)<=S1; SVEC(3)<=S2; V1:=’1’;V2:=’1’;S2<=’1’;SVEC(4)<=V1; SVEC(5)<=V2; SVEC(6)<=S1; SVEC(7)<=S2; END PROCESS;
选项：

A:11100010;
B:00011101;
C:00001101;
D:11110010
