Sight distance depends upon height of the headlight i.e. 0.75m in turn is used only in nighttime driving condition.

Option D is Wrong because road alignment is considered into height of driver.

Answer c should be correct. Because according to the relation L= NS2/2h+2stan (α).

Alpha should be always 1 as per IRC. So hear, if we find out "h" i.e. height of the driver then we can get SSD easily.
