The answer is - Sunspots.
Sunspots are dark in appearance, but only on a visible light, and this is due to the fact that they are much cooler than the surrounding areas, but that doesn't mean by any means that the sunspots are cool, on contrary, they are very hot too. Sunspots actually are storms that appear in the lower atmosphere of the sun.
Answer: Option (1)
Explanation: In an occluded front, the cold air overtakes or completely replaces the warm air in the atmosphere. It generally forms at the region where the atmospheric pressure is relatively low.
Due to the presence of an occluded front, the direction of wind and the temperature varies i.e the temperature could be high or low and the wind may be strong or weak. in addition to that there might be occurrence of a heavy rainfall as well as thunderstorms.
Thus the correct answer is option (1).
Since this is a square you can set 3x+20=5x then you can solve for x.
Subtract 3x from both sides:
3x-3x+20=5x-3x
20=2x
Divide both sides by 2
20/2=2x/2
10=x
Hope this helps.
