The Hubble type used for unbarred spiral galaxies with loosely wound arms is Sc.

Here's a step-by-step explanation:

1. Edwin Hubble created a classification system for galaxies, known as the Hubble sequence or Hubble's tuning fork diagram.

2. This system classifies galaxies based on their visual appearance. There are four main types: elliptical galaxies (E), spiral galaxies (S), barred spiral galaxies (SB), and irregular galaxies (Irr).

3. Spiral galaxies are further divided into categories a, b, and c, based on how tightly their arms are wound.

4. Type 'a' has tightly wound arms, 'b' has moderately wound arms, and 'c' has loosely wound arms.

5. The prefix 'S' stands for spiral galaxies that are unbarred, and 'SB' stands for spiral galaxies that are barred.

6. Therefore, the Hubble type for unbarred spiral galaxies with loosely wound arms is Sc.
