which of the following provides the same protection as safety glasses?

None of the options such as regular glasses, sunglasses, or bifocals provide the same protection as safety glasses. Safety glasses are specifically designed to protect the eyes from impact and debris in hazardous environments with features like impact resistance and coverage that ordinary glasses lack. Alternatives that provide comparable protection would typically be safety goggles or prescription safety glasses that meet safety standards like ANSI Z87.1, but regular eyewear does not offer this level of protection.
