The correct answers are A) band that is playing, B) date of the concert and C) price of the ticket.
The following items determine my preference for a concert ticket: the band that is playing, date of the concert and price of the ticket.
When deciding on going to a concert, the most important the decision is the band that will be playing. If you are a fan of the band you want to attend the concert. The price of the ticket is also very important and nowadays it goes hand in hand with the artist because today, concert tickets are very pricy. And if you would like to buy a special package that includes "meet and greet" options, photos, and autographs, the price is higher, The date is important in that you have to have that date available with no other compromises.
