Answer 1

In music, a minor triad consists of a root, a minor third, and a fifth; an augmented triad has a raised fifth; a diminished triad has a flat third and flat fifth; a sus2 replaces the third with a second, and a sus4 replaces the third with a fourth. The correct scale degrees for each are (b) Do, Mi, Sol for minor, (c) Do, Mi, Si for augmented, (d) Mi, Sol, La for diminished, (a) Do, Re, Sol for sus2, and there is a typo for sus4, it should be Do, Fa, Sol.

Step-by-step explanation:

Understanding Triads in Music

To spell a minor triad using scale degrees, we look for the combination of the first (root), flat third, and fifth notes of the major scale. The correct option based on scale degrees is (b) Do, Mi, Sol, where 'Mi' is lowered a half step to make it a minor third interval from 'Do'.

An augmented triad is formed by raising the fifth scale degree one half step from a major triad. Therefore, the correct spelling using scale degrees is (c) Do, Mi, Si.

To spell a diminished triad using scale degrees, we take the first, flat third, and flat fifth notes of the major scale. The correct option is (d) Mi, Sol, La, with 'Sol' and 'La' both being lowered a half step.

A sus2 triad replaces the third of a major triad with the second scale degree. Thus, the correct spelling is (a) Do, Re, Sol.

For a sus4 triad, we replace the third scale degree with the fourth. The correct option is therefore (d) Do, Mi, Sol with 'Mi' replaced by 'Fa' (which might be a typo in the options provided).
