Which out of the following is a macromolecular and multimolecular colloid ? Starch sol, sulfur sol.

Explanation

To determine which of the given options is a macromolecular and multimolecular colloid, we need to understand the definitions and characteristics of both types of colloids.

### Step-by-Step Solution:

1. **Understand Colloids**: Colloids are mixtures where one substance is dispersed evenly throughout another. They can be classified into different types based on the size of the dispersed particles.

2. **Define Macromolecular Colloids**: Macromolecular colloids consist of large particles that are typically formed from high molecular mass compounds. These particles are large enough to be considered colloidal and usually have dimensions in the colloidal range (1 nm to 1000 nm). They are often lyophilic (solvent-loving), meaning they have a strong attraction to the solvent.
