Program Question

Hello all:
Newb here and I’m hoping someone can answer a very basic question about programming for me. When a program is laid out like this:

Monday
A. Exercise
B. Exercise
C1. Exercise
C2. Exercise
D. Exercise

Tuesday…

What is the C1 and C2? I don’t understand if they’re alternatives or supersets or what?

Thanks in advance!

Usually it’s meant as a superset
