Which of the following is the best source of protein a. nuts b. fish c. peanut butter d. beans

I think that Fish is one of the best source of protein but also nuts and peanut butter are also a good source of protein.

The answer is definately not beans because beans give you fiber and they have no protein in them.

i don't think so because different teachers have different materials. tehy teach differently, unless you know for sure your teacher is the exact same as others. i would just contact ur teacher
