Given information;
\(R =1\)
\(W =3\)
\(B =2\)
Case 1:
\(R - - - - \frac{W}{B}\) Only \(W\) is possible in the last position. If \(B\) takes the last position then it violates the condition.
Case 2:
\(W - - - - \frac{R}{B}\) possible combinations are \(W B W B W R\) ; \(W R W B W B\) ; \(W B W R W B\)
Case 3:
\(B - - - - \frac{R}{W}\) possible combinations are \(B W B W R W\) \(B W R W B W\)

There are 6 flags and as adjacent flags have to be different, 1st and 6th are the conditions that need to be fulfilled first.A. 48
B. 10
C. 6
D. 4
E. 2
Since three color are there, following are the ways that condition can exist:
1. RW or WR
3. BW or WB
The inner flags can be arranged in many ways in the third case such that it has 4 ways.
Now, flags can be arranged(keeping all different colored flags together) in -
RWBWBW i.e. 1*3*2*2*1*1 = 12
OR
BWBWRW i.e. 2*3*1*2*1*1 = 12
OR
WBWRWB i.e. 2*3*1*2*1*1 = 12
But there are reverse of each of the cases that are also exact copies of the original sequence.
Hence uniquely arranged cases are \(\frac{12}{2} = 6\)
Answer C.
