(1) x is not a prime number.

(2) 2x has less than 3 factors.

Given, $$\frac{x}{9}=f$$, where 0<f<1
This hold when x is less than 9 and x is a positive integer.
So, possible integer values of x: 1,2,3,4,5,6,7,8

St1:- x is not a prime number.
Possible values of x: 1,4,6, and 8
No unique value of x.
Therefore, insufficient.

St2:- 2x has less than 3 factors
2x: 1*2,2*2,3*2,4*2,5*2,6*2,7*2,8*2

Only 2 has two factors, viz, 1 &2 at x=1.

We have obtained an unique value of x,

Therefore, sufficient.

Ans. (B)
