Option E)
Given: q>1, q=?
I: q belongs to {0,9}; q = m*n such that m & n are distinct digits i.e., m & n belong to {0,9}
: q = 1*2 or 1*3 or 1*4 or..or 2*1 or 2*3 or ...
Multiple values possible - Insufficient
II: q has only one odd factor
: q = 2; factors = 1, 2 one odd factor
: q = 4; factors = 1, 2, 4 one odd factor
: q = 8; factors = 1, 2, 4, 8 one odd factor
Multiple values possible - Insufficient
I + II:
: q = 2 = 1*2 [1,2] one odd factor
: q = 3 = 1*3 [1,3] two odd factors
: q = 4 = 1*4 [1,2,4] one odd factor
: q = 5 = 1*5 [1,5] two odd factors

]If q > 1, what is the value of integer q?
(1) q is a digit that is the product of two other distinct digits.
This tells us that q is <10 and also that q can be written as product of two other distinct digits...
The word OTHER tells us that one of these two distinct digits cannot be 1, as 1*2=2.. so here 2 is repeated
So possiblities...
A) 2*3=6
B)2*4=8
So q can be 6 or 8
Insufficient
(2) q has only one odd factor.
Can be many possibilities
Insufficient
Combined..
6 has 1,2,3,6 as factors, so TWO odd factors.. out
8 has 1,2,4,8, so only 1 odd factor..
Ans is 8
