Case 1
Tue - Tuna(T), Mahi Mahi (MM)
Wed - T
Thus - T, MM
Fri - x Halibut (H), T
Sat - H, Snapper (S), MM
Sun - H, S, T

Case II
Tue - T
Wed - T, MM
Thus - T
Fri - x Halibut (H), T, MM
Sat - H, Snapper (S), T
Sun - H, S, MM

Friday and Sunday cannot have the same entrees as one of them has halibut and the other one does not have....option A ruled out...
Option B, C and E are ruled out as they are consecutive days and hence cannot have Mahi Mahi....

Option D is correct

2. Halibut is already being served on Saturday and Sunday. And since it is being served only three no of times... it;ll be served only once during Tue to Thu...
In view of this i dont think any of the opitons is right...

3. option E

4. option E
