a = +, b = +  and c = +  , then which of the following holds true?
i) c > a > b     ii) a > b > c    iii) a > c > b     iv) b > a > c 

The correct answer is: a > b > c

Step 1 of 2:
              a = +
Squaring both sides

   .......  (1)

Squaring both sides

 ..... (2)

Squaring both sides


Step 2 of 2:
We can see that from equation (1) and (2), a² > b² which means a > b, and from equation (2) and (3) b² > c² which means b > c.
Final Answer:
We found that a > b and b > c. So, we can conclude that a > b > c. Hence, option (ii) is correct.

Note: 
This question can simply be solved by finding the values of all the square roots and then using them in finding the values of a, b and c and then their values can be easily compared.
