Which chord progression represents the I, IV, V7 in the key of C on the guitar?

1. A progression in G

2. A progression in C

3. A progression in D

4. A progression in A

The correct answer is: A progression in C

In music theory, a chord progression consisting of I, IV, V7 in the key of C involves specific chords based on the scale of C major. The I chord is the tonic, which is C major. The IV chord is the subdominant, which is F major. The V7 chord is the dominant seventh, which is G7 in this key. This means that, when playing in the key of C, the chords used in this progression would be C (I), F (IV), and G7 (V7). The option indicating a progression in C accurately reflects this, as it includes these major and dominant seventh chords that complete the I-IV-V7 progression, establishing a strong harmonic foundation commonly used in various musical styles. Other keys mentioned do not correspond to the I, IV, V7 chord progression in C. For instance, a progression in G would feature the chords G (I), C (IV), and D7 (V7), while a progression in D would give D (I), G (IV), and A7 (V7). Each of these options features different tonic, subdominant, and dominant chords that do not align with the original question's specified key of C. Thus, recognizing
