Which of the following types of stars started out on the main sequence with the largest initial mass?
In Graph A, the curve peaks at 800 nm, in the red section of the visible light spectrum. In Graph B, the curve peaks at 550 nm, in the green section of the visible light spectrum. In Graph C, the curve peaks at 450 nm, in the blue section of the visible light spectrum. In Graph D, the curve peaks at 300 nm, in the violet section of the visible light spectrum.

To determine which type of stars started out on the main sequence with the largest initial mass, we need to understand the relationship between a star's mass and its position on the main sequence.
The main sequence is a diagonal band on the Hertzsprung-Russell (H-R) diagram, which plots a star's temperature against its luminosity. Generally, stars on the main sequence with higher masses have higher temperatures and higher luminosities.
Given the information provided, we can deduce the following:
- Graph A: The curve peaks at 800 nm, in the red section of the visible light spectrum.
- Graph B: The curve peaks at 550 nm, in the green section of the visible light spectrum.
- Graph C: The curve peaks at 450 nm, in the blue section of the visible light spectrum.
- Graph D: The curve peaks at 300 nm, in the violet section of the visible light spectrum.
Since higher temperatures correspond to bluer light and lower temperatures correspond to redder light, we can infer that stars represented by Graph D have the highest temperature, and therefore the highest mass. This makes the answer D the correct option.
Please note that additional information about the graphs, such as their specific labels or accompanying scales, could provide more context and accuracy in determining the answer.
