Answer 1

What's your database version?
That's a funny requirement.
How about :
select case sol.a
          when 'A' then sic.a
          when 'B' then sic.b
          when 'C' then sic.c
          when 'D' then sic.d
       end as a
     , case sol.b
          when 'A' then sic.a
          when 'B' then sic.b
          when 'C' then sic.c
          when 'D' then sic.d
       end as b
     , case sol.c
          when 'A' then sic.a
          when 'B' then sic.b
          when 'C' then sic.c
          when 'D' then sic.d
       end as c
     , case sol.d
          when 'A' then sic.a
          when 'B' then sic.b
          when 'C' then sic.c
          when 'D' then sic.d
       end as d
from sol_k sol, sic_k sic
;XQuery can do the trick too :
SQL> SELECT *
  2  FROM XMLTable(
  3   'for $i in ora:view("SIC_K")/ROW
  4    return element r {
  5     for $j in ora:view("SOL_K")/ROW/child::*
  6     return element {name($j)} {$i/child::*[name()=$j]/text()}
  7    }'
  8   columns
  9     a varchar2(30) path 'A'
10   , b varchar2(30) path 'B'
11   , c varchar2(30) path 'C'
12   , d varchar2(30) path 'D'
13  );
A          B          C          D
           MANOJ      Kamal      Micky
