It's B, Bowman's capsule !
Luminosity or magnitude of energy brightness
I guess so it can be easier to understand. sorry if this wrong im sorry . but this is my answer
I believe solar power is a renewable energy source that should develop first. This is because as of right now, scientists know that they aren't as efficient as they could be. These panels are currently growing cheaper as production capabilities increases but the panels are going to rarely be able to produce efficiently due to weather conditions. If more money gets added to the research and development of this technology, these panels will become more efficient, thus making more clean energy.
