Answer 1

It would certainly help with some more details on the business rules.
I am puzzled over these two rows:
insert into @myTable values ('Bull Bar'   ,'Ford','F-250',   '1997',   'Four Wheel Drive',   'NR-301')  
   --All element from a group of PT,MK,MO,YR should be Removed from output, as Part  1330371971 is not available with all the remarks available in a group. (1330371971 is not available with Rear Wheel Drive.)
insert into @myTable values ('Bull Bar'   ,'Ford','F-250',   '1997',   'Rear Wheel Drive',   'NR-301')  
   --All element from a group of PT,MK,MO,YR should be Removed from output, as Part  1330371971 is not available with all the remarks available in a group. (1330371971 is not available with Rear Wheel Drive.)
Overlooking the fact that the part number in the comment does not match, how this is different from parts 51C and 51X which also has a Four Wheel Drive and a Rear Wheel Drive?
I guess the real question is how do I know what "all available options" are? I would kind of expect a table which defines this.
