Answer 1

Given:

A cluster of number: 85624731

According to the given cluster, condition number 2 should be implemented.

If the first digit is even and the last digit is odd, both are to be coded by the code for the first digit.

So, 85624731 will be coded as

Number/digit	8	5	6	2	4	7	3	1
Code	#	K	&	F	$	D	^	#

Thus, the required code will be #K&F$D^#

Hence, "Option 2" is the correct answer.
