Here's a table of the possible product outcomes

 

       1    2   3   4   5   6

1     O   E   O  E   O  E

2     E    E   E  E   E   E  

3     O   E   O  E   O  E

4     E    E   E  E   E  E

5     O   E   O  E   O  E

6     E   E    E  E   E  E

 

We have 27  even outcomes and  9  odd outcomes

 

Option One Expectation

 

(4)(27/36) - (8)(9/36)   =  (4)(3/4)  - (8)(1/4)  =  3 - 2  =   1

 

Option Two Expectation

 

(5)(27/36) - (9)(9/36)  =  (5)(3/4) - 9(1/4)  =  15/4 - 9/4  =  6/4  =  3/2  = 1.5

 

 

So....Option Two is better  [Second Answer ]
