Пусть дано:      type m =  set of char;                             var  a,b,c : m;                              begin                                   a := [‘a’, ‘k’, ‘l’, ‘m’, ‘n’];   b:=[ ‘k’, ‘m’, ‘n’, ‘p’];                                                         c := a - b;                               end. Что будет находиться в c?


1) [ ‘a’, ‘k’, ‘l’, ‘m’, ‘n’]         

2) [‘k’, ‘m’, ‘n’, ‘p’]     

3) [ ‘a’, ‘k’, ‘l’, ‘m’, ‘n’, ‘p’]

4) [ ‘a’, ‘l’ ,‘p’]                      

5) [ ‘a’, ‘l’]
