Answer is Right!
Answer is Wrong!
The correct answer is B. 760 mm.
A low passenger platform is a platform that is designed for passengers to board and alight from trains without having to climb steps. The maximum height above rail level for a low passenger platform in BG is 760 mm. This means that the platform must be at least 760 mm above the level of the rail, so that passengers can easily step on and off the train.
Option A is incorrect because the maximum height above rail level for a low passenger platform in BG is 760 mm, not 455 mm.
Option C is incorrect because the maximum height above rail level for a low passenger platform in BG is 760 mm, not 840 mm.
Option D is incorrect because there is a correct answer to the question.
