The following pseudocode is executed using the "Library" dataset. At the end of the execution, `A` captures the number of pairs of books which are published in the same genre and in the same year but in different languages. But the pseudocode may have mistakes. Identify all such mistakes (if any). Assume that all statements not listed in the options below are free of errors.
```
A = 0
while(Table 1 has more rows){
Read the first row X from Table 1
Move X to Table 2
while(Table 1 has more rows){
Read the first row Y from Table 1
B = False, C = False, D = True
if(X.Genre == Y.Genre){
B = True
}
if(X.Year == Y.Year){
C = True
}
if(X.Language == Y.Language){
D = False
}
if(B and C and D){
A = A + 1
}
Move Y to Table 3
