The answer is simply: A the other person is too confusing...
The Sun is the object in space that emits light due to the energy released from nuclear fusion in its core. This process involves the fusion of hydrogen nuclei to form helium, releasing energy as photons, neutrinos, and gamma rays. The released energy, particularly the photons, is therefore responsible for the Sun's light.
The object in space that emits light because it releases energy produced by nuclear fusion is the Sun. This nuclear fusion takes place in the Sun’s core and involves the combination of two hydrogen nuclei to form helium, releasing energy in the process. This energy is released as light and other particles such as neutrinos and gamma rays.
In detail, the nuclear fusion reaction in the Sun converts about 10³8 protons per second into helium at a temperature of 14 million Kelvin. The energy produced manifests as photons (light), neutrinos, and other particles. The neutrinos and gamma rays escape the Sun's core and propagate out into space.
The energy from this nuclear fusion diffuses slowly towards the surface of the Sun, lighting up the Sun and ultimately, our Earth. It's worth noting that though this process destroys mass, the amount of energy release, known as the Q value, is incredibly large, affirming the application of Einstein's mass-energy equivalence principle, E=mc².

Answer:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Explanation:
hope that helps!
B. Telophase
C. Interphase
He observes the formation of a cell plate. He is observing the phase of the cell cycle Cytokinesis.
Mitosis is used to produce daughter cells that are genetically identical to the parent cells which produces two daughter cells from one parent cell, during it division,shorter cell cycles occur in early embryo cells this later result to the daughter cells been smaller than the mother cell in the embryonic cell cycles
Thus, option "A" is correct.
