From statement 1st it is not mention that Y is integer or not so we don't have a unique value of Y, Y can 10,10.3,10.5,....
From statement 2nd Y can be -10 or 10 and it is mention than Y is positive then we have a unique value here
Answer is [B].

y is positive, but y is not necessarily an integer.
(A) Only
Y can be 10, 10.1, 10.01, 10.001, etc.
Not sufficient.
(B) Only
|y| = 10
Because y is positive, it can only be 10.
Sufficient.
The answer is thus (B).
