The following pseudocode is executed using the "Library" dataset. What does the count represent at the end of execution? D = { }, count = 0 while (Table 1 has more rows) { Read the first row X from Table 1 if (isKey(D, X.Author)) { D[X.Author] = D[X.Author] ++ [X.Name] } else { D[X.Author] = [X.Name] } Move the row X to Table 2 } foreach i in keys (D) { if (length(D[i]) > 2) { count = count +1 } }

(D) Number of authors who wrote more than two books.

(A) Number of pairs of authors who wrote more than two books.
