If integers ending in zero are excluded, what is the unit digit of the product of the even integers from 802 to 898, inclusive?  Choose the most appropriate option:
A) 14  B) 12  C) 10  D) 6  E) 8
802 x 804 x 806 x 808 =&gt; unit digit 4   812 x 814 x 816 x 818 =&gt; unit digit 4   892 x 894 x 896 x 898 =&gt; unit digit 4   So we have 10 numbers ending by 4 to multiply.   Given that 4 x 4 = 16, we have 5 numbers ending by 6 to multiply   Given that 6 x 6 = 36, we have 3 numbers ending by 6 to multiply   So the unit digit is 6   Answer : 6
