The transparency of glass is attributed to which of the following properties of glass?

Options

A. High viscosity
B. Regular pattern of arrangement of silicate units
C. Irregular pattern of arrangement of silicate units
D. High cocfficient of thermal expansion

Explanation

To determine the property of glass that contributes to its transparency, let's analyze the options provided step by step.

### Step 1: Understand the properties of glass
Glass is a solid material that is typically transparent. Its transparency is a key characteristic that allows light to pass through it.

### Step 2: Evaluate the options
1. **High viscosity**: This refers to a material's resistance to flow. Glass does not have high viscosity in the context of its transparency.
