Directions: In the question given below, a passage is given followed by five statements. Read the information and answer the question that follows.

The Railways will soon install an optical fiber-based intrusion detection system (IDs) along the elephant-infested 33-km stretch between Kottelkkad and Madukkarai to prevent elephant deaths on the tracks. The Southern Railway is installing the system for the first time after its successful implementation in the Northeast Frontier Railway(NFR). 

Which of the following strengthens the following statement?

I) According to the railway official, the project is likely to be costlier as it involves the laying of optical fiber cables along both sides of the rail lines.

II) The exact location of the elephants will be passed to loco pilots and station masters with the help of optics.

III) Due to the lack of railway land the fiber is laid close to the tracks, so loco pilots may not get enough time to respond to an alarm.

IV) As this project is new for the officials this will take at least two years for the proper implementation of the project.

V) It will take time to design the signals in such a way that it can signal for a variety of animals as well as vehicles.
