Proteins are made up of long chains of amino acids, which can fold into a variety of shapes. The correct shape of a protein is critical for its function. Chaperones are proteins that assist in the correct folding of other proteins. Therefore, choice B is the best answer as it correctly highlights the need for chaperones for proteins to assume the correct shape. Choices A, C, D, and E are incorrect because they are either incorrect (choice A) or include incorrect information about polarity (choices C and D) or the number of functional shapes a protein can assume (choice E).
