The telluric helix was given by

Options

A. Newlands
B. Mendeleev
C. Lothar Meyer
D. Dechen Courtious

Explanation

To solve the question "The telluric helix was given by," we need to analyze the options provided and identify the scientist associated with the telluric helix.

### Step-by-Step Solution:

1. **Understand the Term "Telluric Helix":**
- The term "telluric helix" refers to a specific arrangement of elements in a helical or spiral form, which is a unique way of classifying elements based on their properties.

2. **Examine the Options:**
- **Option A: Newland** - Known for the Law of Octaves, where he arranged elements in ascending order of atomic mass and noted that every eighth element had similar properties.
- **Option B: Mendeleev** - Developed the periodic table based on atomic mass and predicted the properties of undiscovered elements.
- **Option C: Lothar Meyer** - Also arranged elements based on atomic mass and physical properties but did not create a helical arrangement.
- **Option D: D. Chan-Cortoise** - This scientist is credited with arranging elements in a helical form, which aligns with the term "telluric helix."

3. **Identify the Correct Answer:**
- Based on the descriptions, D. Chan-Cortoise is the scientist who introduced the telluric helix. Therefore, the correct answer is **Option D: D. Chan-Cortoise**.

### Final Answer:
The telluric helix was given by **D. Chan-Cortoise**.
