Consider the following statements: (a) Fiber optic cable is much lighter than…

Answer: Only (a) and (b) are correct.

Explanation:

• Statement (a): Fiber optic cable is much lighter than copper cable — true. Fiber uses glass or plastic cores and much less metal, so the mass per unit length is lower than copper conductors.

• Statement (b): Fiber optic cable is not affected by power surges or electromagnetic interference — true. Fiber is dielectric (non‑conductive), so it does not pick up electrical noise or conduct surge currents the way metal cables do.

• Statement (c): Optical transmission is inherently bidirectional — false. Light in a fiber travels in a particular direction; two‑way communication is achieved by using two separate fibers (one for each direction), by using different wavelengths for transmit and receive on the same fiber, or with special bidirectional hardware. That means bidirectional operation is possible but not inherent to a single fiber.

Therefore select the option that states only statements (a) and (b) are correct.
