What type of fiber optic cable is manufactured to protect individual glass strands and is primarily designed for use inside buildings?
The correct answer is B. Tight buffered. In tight-buffered fiber optic cable, a hard plastic coating is applied directly and tightly over each individual glass fiber strand, providing mechanical protection and making it easier to handle, terminate, and route inside buildings.

Explanation
In tight-buffered fiber optic cable, a hard plastic coating is applied directly and tightly over each individual glass fiber strand, providing mechanical protection and making it easier to handle, terminate, and route inside buildings. This construction is ideal for indoor environments where the cable may be bent around corners or terminated frequently. Loose-tube cable, by contrast, has fibers floating freely inside a gel-filled tube and is designed for outdoor/OSP use where flexibility against environmental stresses (moisture, temperature swings) is needed. Ribbon cable bundles multiple fibers flat for high-density applications, and air-blown fiber uses pressurized air to push fiber strands through pre-installed microducts - neither is the standard choice for general indoor individual-strand protection.
