which of the following choices is the closest in size to one serving of meat?

Aa coffee mug
Ban open palm
Ca baseball
Da deck of cards

Verified Answer :

I would have to say B. 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. :)

B. an open palm is correct, I think
