Which one of the following choices is the closest in size to one serving meat. a. a coffee mug b. a deck of cards c. an open palmd. a baseball

I would have to say

C. open palm of your hand

Only because it's portions for different size people.

A child portion would be different from an adult portion, and the palm is the only thing that measures by the size of the person.

Hope this helps. :)

the answer is c dandruff
