Correct option**(A) 150**
One possible arrangement is
| 2 | 2 | 1 |
Three such arrangements are possible.
Therefore, the number of ways is
(5C2)(3C2)(1C1)(3) = 90
The other possible arrangement,
| 1 | 1 | 3 |
Three such arrangements are possible.
In this case, the number of ways is
(5C1)(4C1)(3C3)(3) = 60
Hence, the total number of ways is
90 + 60 = 150.
