Select the option that represents the letters that, when sequentially placed from left to right in the blanks below, will complete the letter series.

t u _ _ x _ _ _ u u_ _ x y _ _ _ v x x _

u v x y t v x t u u y

t u _ _ x _ _ _ u u_ _ x y _ _ _ v x x _

The logic here is: The repeated letters used are 'tuuvxxy'. A group of 7 letters is made.

First we will check all the options:

1) u v x y u v x t u u y → t u u v x x y  - u u u v x x y  - t u u v x x y

2) u v x x t v x t u u y → t u u v x x x  - t u u v x x y - t u u v x x y

3) u v x y t v x t u u y → t u u v x x y  - t u u v x x y  - t u u v x x y

pattern is followed

4) u v x y t v x t u u u → t u u v x x y  - t u u v x x y - t u u v x x u

So, in option 3 'u v x y t v x t u u y' is repeating itself.

 'u v x y t v x t u u y' is correct ans .
