Answer:
Option C) Ascending Third
Step-by-step explanation:
Each chord's root is a third higher than the previous chord's root.
Roman Numerals:
I = 1 , II = 2 , III = 3 , IV = 4 , V = 5 , VI = 6 , VII = 7
Sequence:
I - IV - vii - iii - vi -ii - V - I = 1 - 4 - 7 - 3 - 6 - 2 - 5 - 1
Each cord that goes higher is ascending by three
