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 Insufficient

1) Not Sufficient as multiple combinations are possible.
2) Not Sufficient. Q has only one odd factor, implies the no is prime, which has only 1 as a factor apart from itself.
Combining the 2 statements + question stem, we can imply q=2.
1) q>1 2) It's a combo of 2 Distinct digits 2 and 1 3) It has only 1 odd factor I.e 1
Answer is C

If q > 1, what is the value of integer q? Option 1: q is a digit that is the product of two other distinct digits.... q can be 12=3*4, 20=4*5... Not sufficient.
Option 2: q has only one odd factor. Here also, there are multiple combination like option 1.. Not sufficient..
Together, We can prove this as sufficient.. Answer is C...

Combined: The only number which is a single digit and has odd factor is 6 (6=2*3 and 3 is odd factor). Answer is C.

If q > 1, what is the value of integer q?
(1) q is a digit that is the product of two other distinct digits. 2*3 = 6 or 2*4=8 NS (2) q has only one odd factor. 1*2 =2 1*4 =4 1*200=200 ...NS
(1)+(2) 2*4=8 (only one odd factor of digit 8 is 1)
Answer (C)

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 Insufficient I believe 1*2,...,1*8 cannot be considered while considering (1)+(2) since (1) states that q is a digit which is a multiple of two "other distinct" digits. Hence, answer should be C. Only 2*4=8 is valid. Please let me know if my reasoning is incorrect.

]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 Sufficient

Thanks Hi Statement I gives q as a digit.. And there are only 10 digits  0,1,2,3,4,5,6,7,8,9 Above 9, we are looking at 2digit (10,11,56,99), 3digit numbers(100,111,...999) So q<10
