From the following table, identify the wrong answer in terms of Range (ft).

In CEH v13 Module 11: Hacking Wireless Networks, wireless standards and their transmission ranges are discussed.

Actual Range Specs:

802.11a: Operates at 5 GHz, range up to ~75 ft indoors, much less than 150 ft due to poor wall penetration.

802.11b/g: Operate at 2.4 GHz, typically 150–300 ft indoors.

802.16 (WiMax): Wireless MAN technology with range up to 30 miles — correct for point-to-point outdoor line of sight.

Conclusion:

802.11a listed as 150–150 ft is incorrect.

Realistic effective range is up to 75 ft indoors, depending on obstructions and interference.

This overestimation makes Option D the wrong one.
