Among the options provided, the correct answer is (B) DMSO. DMSO, or dimethyl sulfoxide, is widely recognized as a cryoprotectant, which helps protect biological tissues during freezing. While mannitol is used in some contexts, it is not primarily classified as a cryoprotectant. Ethylene oxide is mainly used for sterilization purposes. Therefore, the best choice here is DMSO.
