the answer is 
using the factoral calculator, we can find
4! x 3! x 1! = (4x3x2x1) x(3x2x1) x (1)= 24* 6 * 1 = 144
it will be placed side by side (two manners)
so it will be 2 x 144 = 288 different color patterns
the answer is A. 288

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Total number of blocks = 8

Number of white blocks = 4

Number of yellow blocks = 3

Number of purple blocks = 1

According to question, we need to place the blocks side by side in a straight manner ,

So, Number of different colors pattern will be

[tex]4!\times 3!\times 1!\\\\ =4\times 3\times 2\times 1\times 3\times 2\times 1\times 1\\\\=144[/tex]

Since there are two ways to written in a straight lines so, the total number of different color patterns he could make is given by

[tex]2\times 144=288[/tex]

Hence, there are 288 ways to make different color patterns .

Therefore, Option 'A' is correct.
