put all the results that in to set object which wont allow duplicates and then print the set
or you can use contains(Object o) of set and loop just once
if contains is true then you wont display
if it is not true then you will display ans add to the set
if contains is true then you wont display
if it is not true then you will display ans add to the set

Hmm New Question Prince :)
since it is in one <option> tag you can get what you are looking for but it will be having 6 option lines instead of two
BIG -- DNS -- V1.0
V2.0
V3.0
ABC -- INS -- V4.5
V5.5
V5.5
when you find the similar string you do not print rest of the time you print it.But it is up to you how you want the design to be

Dont want user to select wrong family maping to wrong product maping wrong version and vice-versa.
