In a major key, major triads can be built on the first, fourth, and fifth scale degrees.

So, the correct answer is "all of the above."

To determine which scale degrees can major triads be built on in a major key, we need to understand the structure of a major scale and how triads are constructed.

A major scale follows a specific pattern of whole steps (W) and half steps (H). The pattern for a major scale is: W-W-H-W-W-W-H. For example, in the key of C major, the notes would be: C-D-E-F-G-A-B-C.

A triad is a three-note chord consisting of a root, a third, and a fifth. Building a major triad involves taking the root note of the triad, the third note from the root, and the fifth note from the root of the major scale.

In a major key, major triads can be built on the first (tonic), fourth (subdominant), and fifth (dominant) scale degrees. These are also known as the I, IV, and V chords respectively.

Therefore, the correct answer is "all of the above" since major triads can be built on the first, fourth, and fifth scale degrees in a major key.
