Answer:
Option A
Explanation:
Corona is defined by the strong magnetic fields. When these strong magnetic fields confine solar atmosphere and produces violent bubble of gases then it is said to cause coronal mass ejection (CME).  
When a CME passes through the solar wind, it causes production of high velocity solar energetic particles that follow magnetic field lines and passes through the space between the Sun and the Earth. The charged particle added by CME intensifies the solar wind.  
Hence, option A is correct
 
        
             
        
        
        
In general, the function of the excretory system is,  removal of nitrogen waste products from the bloodstream and transport out of the body through urine. It maintains the balance of fluids and electrolytes, control of red blood cells, regulation of blood pressure and also the formation of red bone marrow.
In humans, the excretory system is responsible for removing waste from the body. Metabolic waste is being removed from the blood and an appropriate amount of water nutrients and water and salt are being retained.
In frogs, the excretory system consists of a pair of ureters, kidney pairs, cloaca, and urinary bladder. Frogs take in liquid waste from kidney which removes wastes and then the extra water becomes urine which then it is collected in the urinary bladder through ureters.
The urinary bladder is present in ventral to return then both open into the cloaca.

 Answer:
The correct option for the phenotypic ratio in this case is the following
9 : 6 : 1  
Explanation:
In order to calculate the ratio, divide the two larger numbers each by the smallest one - which here would be 17.
So, 147 ÷ 17 = 8.7 (rounded off to 9)
And 93 ÷ 17 = 5.6 (rounded off to 6) 
This way, '17' is considered as 1. Hence,
Gold : silver : bronze
    9   :     6   :    1
