The characteristic, shared by sunspots, solar flares, and coronal mass ejections, are :
- They appear as dark spots on the sun's surface.
- They tend to occur during active periods of the solar cycle.
What is the solar cycle?
- The solar cycle, also known as the solar magnetic activity cycle, sunspot cycle, or Schwabe cycle, is a nearly periodic 11-year change in the Sun's activity measured in terms of variations in the number of observed sunspots on the Sun's surface.
- Over the period of a solar cycle, levels of solar radiation and ejection of solar material, the number and size of sunspots, solar flares, and coronal loops all exhibit a synchronized fluctuation from a period of minimum activity to a period of a maximum activity back to a period of minimum activity.
- This cycle has been observed for centuries by changes in the Sun's appearance and by terrestrial phenomena such as aurora but was not clearly identified until 1843.
- Solar activity, driven by both the solar cycle and transient aperiodic processes, governs the environment of interplanetary space by creating space weather and impacting space- and ground-based technologies as well as the Earth's atmosphere and also possibly climate fluctuations on scales of centuries and longer.

IDEA talks about TBI to be an injury, acquired, which affects the brain as a result of the physical force, which comes externally, causing total or partial impairment in areas such as cognition, language, problem-solving, psycho-social behavior; physical functions; information processing; and speech.
Answer: <em>Option (C) is correct.</em>
Explanation:
Ethics which is at times known as moral philosophy is referred as a arm of philosophy which tends to involve defending, systematizing, and thus recommending notion of wrong and right conduct.
