**Question 6:**

A molecule of a compound has the absorption spectrum shown below. Which peak in this curve corresponds to the lowest-energy transition by an electron?

- A) 420 nm
- B) 500 nm
- C) 610 nm
- D) 650 nm

**Description of the Diagram:**

The diagram displays an absorption spectrum graph with various peaks. The x-axis represents wavelength in nanometers (nm), ranging from approximately 400 nm to 700 nm. The y-axis represents the unit of absorbance. A color gradient spans the top of the graph, from violet at the shorter wavelengths to red at the longer wavelengths. Two prominent peaks are visible near 420 nm and 650 nm, indicating higher absorbance at these wavelengths. The task is to identify which peak corresponds to the lowest-energy transition, inferred to be at the longest wavelength (650 nm).
