about 11 years

about 76 years

between 25 and 35 days
D
365.25 days
E
about seven years
Explanation: 

Detailed explanation-1: -The 11-year sunspot cycle is actually half of a longer, 22-year cycle of solar activity During this period, sunspot counts reach maximum and minimum twice.

Detailed explanation-2: -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.

Detailed explanation-3: -The solar cycle describes an approximately 11-year cycle of solar activity driven by the sun’s magnetic field and indicated by the frequency and intensity of sunspots visible on the surface.

Detailed explanation-4: -The Solar Cycle: Sunspots increase and decrease through an average cycle of 11 years. Dating back to 1749, we have experienced 23 full solar cycles where the number of sunspots have gone from a minimum, to a maximum and back to the next minimum, through approximate 11 year cycles.

Detailed explanation-5: -Every 11 years the Sun’s magnetic cycle ramps up into overdrive. At the height of this cycle, known as solar maximum, the Sun’s magnetic poles flip. Along the way, changes in the Sun’s magnetism produce a greater number of sunspots, more energy and cause solar eruptions of particles.

Detailed explanation-6: -The Sun has its ups and downs and cycles between them regularly. Roughly every 11 years, at the height of this cycle, the Sun’s magnetic poles flip-on Earth, that’d be like if the North and South Poles swapped places every decade-and the Sun transitions from sluggish to active and stormy.
