B and C would be necessary.
The cool thing about triangle congruency postulates is that their names are in coordination with how they work.
Take, in this case, SAS. Since the A is in between two S's, you can infer that an angle has to be between two sides.
For ASA, the S is in between the two A's, and so you can infer that there has to be a side between two angles.
In this scenario, you have to utilize Options B and C in order to ensure an SAS.
If you have any questions, just ask :)
