IMO E

Stmt A: the statement satisfies when y is negative or between 0 and 1. Not sufficient
Stmt B: Nothing is known about Z. Not Sufficient

Combining the statement also not suffient to conclude.

i think from 2nd stmt, we know y is not negative. so it shud be between 0 and 1.

1)

y < -1, or 0 < y < 1

NS

2)

y = z^2

y > 0

NS

1+2)

Given y < -1 or 0 < y < 1
and y > 0

then, 0 < y < 1

(1)
$$y<1/y$$

$$y^2<1, y>0$$
$$y^2>1, y<0$$

$$0<y<1, y<-1$$
So, we could not say whether 0<y<1.

(2)
$$y=z^2$$
This means that y>0 (since yz is not 0), but we do not know whether y>1 or not.

(1) and (2) together
$$y<-1, 0<y<1 and y>0$$
$$0<y<1$$

So, tho statements together are sufficient.
