Answer: D. False, you can either play a V chord if you want to repeat the pattern or a I chord if you want to end it.
Step-by-step explanation:
In the 12-bar blues, the most common chord progression consists of playing the I, IV, and V chords in various orders. The last bar is typically either the I chord if you want to repeat the pattern, or the V chord if you want to end it. Playing the V chord in the last bar provides a strong sense of resolution and closure while playing the I chord allows for the pattern to continue.
