A group of numbers and symbols is coded using letter codes as per the codes given below and the conditions that follow. Study the given codes and conditions and answer the question that follows.
Note: If none of the conditions apply, then codes for the respective number/symbol are to be followed directly as given in the table.

Number/Symbols	4	@	7	#	3	&	8	*	2	^	9
Code	H	A	J	B	K	C	L	D	M	E	N

Conditions:
i) If the first element is a number and the last a symbol, the codes for these two (the first and the last elements) are to be interchanged.
ii) If the first element is an even number and the last an odd number, the first and last elements are to be coded as .
iii) If both the second and third elements are perfect cubes, then the code of the second element will be the code of the third element.
What will be the code for the following group?
348@

Given:

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

True, first element is a number and the last a symbol first and the last elements are to be interchanged. So, the code is A48K.
ii) If the first element is an even number and the last an odd number, the first and last elements are to be coded as.

False, first and last element is not an even number and an odd number.
iii) If both the second and third elements are perfect cubes, then the code of the second element will be the code of the third element.

False, both the second and third elements are not perfect cubes.
So, the code of 348@ is AHLK.

Thus, correct option is (d).
