Conditions:
i. If the first element is a prime number and the last element is an even number, then the codes for these two (first and last elements) are to be interchanged.
ii. If the third element is a symbol, then it is to be coded as α.
iii. If both the second and the fourth elements are perfect square, then the fourth number is to be coded as the code for the second element.
What will be the code for the following group?
3 ÷ 7 @ 4

Given:

Conditions:
i. If the first element is a prime number and the last element is an even number, then the codes for these two (first and last elements) are to be interchanged. True 

So, the code is T ÷ 7 @ A.

ii. If the third element is a symbol, then it is to be coded as α. False,

iii. If both the second and the fourth elements are perfect square, then the fourth number is to be coded as the code for the second element. False

So, the code of 3 ÷ 7 @ 4 is T E S W A.

Thus, correct option is (d).
