Answer 1

I believe the compositional styles matched with characteristics are:

a. Organum: a composition of two or more voices, one of which is based on a previously existing chant melody.
Organum represents an early type of polyphonic music based on plainsong. In contrast to Gregorian chant, organum has an accompaniment.

b. Gregorian chant: monophonic melodies compiled by a certain pope.
This chant represent the central tradition of Western plainchant. It is a unaccompanied sacred song of the Roman Catholic Church.

c. Polyphony: any composition using two or more independent voices.
The polyphony is musical texture that combines melodic, rhythmic, and harmonic aspects of a musical composition.
