Answer 1

D, 10lb 6 oz

Please put in correct section next time though.  

Answer 2

E. none of the above

B. is closest and you're on the right track

But ther are only 16 oz. in a pound. 16 of the 20 oz form another pound, leaving you with 4 ounces left over. That said, your answer should be 13 lbs. + 4 oz. (unless your teacher lets you use unlike fractions of 12 and 20 / 16, which could be reduced to 12 and 5 / 4)
