How it depends on the height driver eye if driver is short then.

In valley curves, the design shall be made considering head light sight distance; not the height of driver's eye.

In valley curves two conditions are required-comfort zone (in which the change in centrifugal acceleration is limited upto a certain level).

Safety criteria: In which the driver should have adequate light during night.

So option (D) is correct.
