Sulphur, on heating follows Which of the following sequence?

Options

A. solid `rarr` thick viscous liquid `rarr` thin liquid `rarr` gas
B. solid `rarr` semi solid `rarr` liquid `rarr` gas
C. solid `rarr` thin liquid `rarr` thick viscous `rarr` thin'liquid `rarr` gas
D. solid `rarr` powdery solid `rarr` thick viscous liquid `rarr` gas

Explanation

To determine the sequence that sulfur follows upon heating, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Starting State - Solid Sulfur**:
- When sulfur is at room temperature, it exists as a solid. This is the initial state before any heating occurs.

2. **First Heating - Thin Liquid**:
