A composite circular shaft is comprised of a steel core surrounded by an aluminum annulus, perfectly bonded to each other as shown in the figure. If it subjected to a pure torque, which one of the following statements is TRUE?
(A) Only shear stress is continuous across the steel-aluminum interface
(B) Only shear strain is continuous across the steel-aluminum interface
(C) Both shear stress and shear strain are continuous across the steel-aluminum interface
(D) Both shear stress and shear strain are discontinuous across the steel-aluminum interface
